Get modal popup values in gridview row textbox

I have a gridview with dynamic controls. Resource name is something that I am picking up from Active directory. Search filter works in a way where you have to enter lastname, firstname and onlclick of lookup it will search. If there are more than one record a modalpopup will be displayed with dropdownlist with options to select from.
The issue is that I am unable to get the dropdown values populated into textbox present in gridview. I need this dropdown value in correct selected row's textbox.
Code behind:
protected void gvProjectResource_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Lookup")
{
GridViewRow clickedRow = ((LinkButton)e.CommandSource).NamingContainer as GridViewRow;
TextBox t2 = ((TextBox)clickedRow.FindControl("t2"));
DataTable dt = globalObj.FindPersons(t2.Text.Split(',')[0].Trim(), t2.Text.Split(',')[1].Trim());
if (dt.Rows.Count > 1)
{
mpFindPerson.Show();
ddlPersons.Items.Clear();
ddlPersons.Items.Add(new ListItem { Value = "0", Text = "-Select User-" });
ddlPersons.DataSource = dt;
dt.Columns.Add("FullName", typeof(string), "DisplayName + ' | ' + MSID");
ddlPersons.DataTextField = "FullName";
ddlPersons.DataValueField = "MSID";
ddlPersons.DataBind();
}
else
{
t2.Text = dt.Rows[0].ItemArray[0].ToString();
}
}
if (e.CommandName == "Del")
{
}
}
protected void btnSelectPerson_Click(object sender, EventArgs e)
{
TextBox t2 = (gvProjectResource.SelectedRow.FindControl("t2") as TextBox);
t2.Text = ddlPersons.SelectedItem.Text;
mpFindPerson.Hide();
}

ok, so, there was nothing much to do.
have to add this.

t2.Text = ddlPersons.SelectedItem.Text;
mpFindPerson.Hide();

My TextChange Event and Filling gridview in every text change event:
protected void txt_CandidateSource_TextChanged(object sender, EventArgs e)
{
if (txt_CandidateSource.Text != "")
{
System.Threading.Thread.Sleep(2000);
DataTable dt = new DataTable();
bo.Para1 = txt_CandidateSource.Text;

Why does my asp update panel only refresh once

Hi I have an asp updatePanel which contains several asp panels. The way it should function is you click the button in the first panel it hides that panel and shows the next. That works fine the problem comes with the next panel. If I try and use either of the button controls within that panel nothing happens.
Heres the html
<asp:UpdatePanel runat="server" ChildrenAsTriggers="true">
<ContentTemplate>
<asp:Panel ID="pnlAppRej" runat="server" HorizontalAlign="Center" CssClass="textBox"
Width="85%" Visible="True">
<div style="text-align:left; width:90%">
<asp:Label ID="lblAppRej" runat="server" Text="Label"></asp:Label>
</div>
<asp:Button ID="btnApprove" runat="server" Text="Approve" CssClass="button" Style="margin-right: 20px;
margin-top: 10px" Width="100px" onclick="btnApprove_Click" />
<asp:Button ID="btnReject" runat="server" CssClass="button" Text="Reject" Style="margin-left: 20px"
Width="100px" onclick="btnReject_Click" />
</asp:Panel>
<asp:Panel runat="server" ID="pnlRejCom" Width="85%" Visible="False" CssClass="textBox">
<div style="text-align: left">
Comments<br />
</div>
<asp:TextBox ID="tbRejCom" runat="server" Height="54px" TextMode="MultiLine" Width="95%"
CssClass="textBox" Style="margin-top: 5px" ValidationGroup="rejCom"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="tbRejCom"
ErrorMessage="RequiredFieldValidator" ValidationGroup="rejCom">*</asp:RequiredFieldValidator>
<br />
<div style="text-align: center">
<asp:Button ID="btnBackRejCom" runat="server" CssClass="button" Text="Back" Style="margin-right: 20px;
margin-top: 10px" Width="100px" />
<asp:Button ID="btnDoneRejCom" runat="server" CssClass="button" Text="Done" Style="margin-left: 20px;
margin-top: 10px" Width="100px" ValidationGroup="rejCom"
onclick="btnDoneRejCom_Click" />
</div>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
c# code
protected void btnReject_Click(object sender, EventArgs e)
{
pnlRejCom.Visible = true;
pnlAppRej.Visible = false;
}
protected void btnBackRejCom_Click(object sender, EventArgs e)
{
pnlRejCom.Visible = false;
pnlAppRej.Visible = true;
}
its the btnBackRejCom_Click method which doesnt seem to fire. But I have tested setting the pnlRejCom to visible and the method works fine.
Thanks in advance
Charlie

your problem seems to be different.
I would suggest, delete the
protected void btnBackRejCom_Click(object sender, EventArgs e){}
and again create a new event.
This is what i tried and is working fine now.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:PostBackTrigger ControlID="btnReject" />
<asp:AsyncPostBackTrigger ControlID="btnBackRejCom" />
<asp:PostBackTrigger ControlID="btnDoneRejCom" />
</Triggers>
<ContentTemplate>
<asp:Panel ID="pnlAppRej" runat="server" HorizontalAlign="Center" CssClass="textBox"
Width="85%" Visible="True">
<div style="text-align: left; width: 90%">
<asp:Label ID="lblAppRej" runat="server" Text="Label"></asp:Label>
</div>
<asp:Button ID="btnApprove" runat="server" Text="Approve" CssClass="button" Style="margin-right: 20px; margin-top: 10px"
Width="100px" OnClick="btnApprove_Click" />
<asp:Button ID="btnReject" runat="server" CssClass="button" Text="Reject" Style="margin-left: 20px"
Width="100px" OnClick="btnReject_Click" />
</asp:Panel>
<asp:Panel runat="server" ID="pnlRejCom" Width="85%" Visible="False" CssClass="textBox">
<div style="text-align: left">
Comments<br />
</div>
<asp:TextBox ID="tbRejCom" runat="server" Height="54px" TextMode="MultiLine" Width="95%"
CssClass="textBox" Style="margin-top: 5px" ValidationGroup="rejCom"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="tbRejCom"
ErrorMessage="RequiredFieldValidator" ValidationGroup="rejCom">*</asp:RequiredFieldValidator>
<br />
<div style="text-align: center">
<asp:Button ID="btnBackRejCom" runat="server" CssClass="button" Text="Back" Style="margin-right: 20px; margin-top: 10px"
Width="100px" OnClick="btnBackRejCom_Click1" />
<asp:Button ID="btnDoneRejCom" runat="server" CssClass="button" Text="Done" Style="margin-left: 20px; margin-top: 10px"
Width="100px" ValidationGroup="rejCom"
OnClick="btnDoneRejCom_Click" />
</div>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
code behind :
protected void btnBackRejCom_Click1(object sender, EventArgs e)
{
pnlRejCom.Visible = false;
pnlAppRej.Visible = true;
}
Hope this helps. Happy Coding..!!!

I have same problem so I have just added CausesValidation="False" then it works fine for me.so please add CausesValidation in btnBackRejCom button like as below
Please try it
<asp:Button ID="btnBackRejCom" runat="server" CausesValidation="False" CssClass="button" Text="Back" Style="margin-right: 20px;
margin-top: 10px" Width="100px" />
I think It works for you :)

Gridview RowCommand not Fire on Server but works Locally

Gridview RowCommand not fire on server but when i use it on local system it works.But when i publish and post to server RowCommand not fired..shall u give me an solution for this...This is my Grid view Code.
Aspx code:
<asp:GridView ID="gvCandiList" runat="server" Style="border: 1px;" RowStyle-BorderColor="#ebf3e4"ViewStateMode="Enabled" RowStyle-BorderStyle="None" GridLines="Both" PageSize="10" AllowPaging="true" AutoGenerateColumns="false" Width="100%" AlternatingRowStyle-BackColor="" CssClass="grdCandList" RowStyle-CssClass="RowStyle" AlternatingRowStyle-CssClass="AltRowStyle" HeaderStyle-CssClass="grdheaderCandList"

ASPX.CS
protected void gvCandiList_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("View"))
{
Session["CandiUserId"] = e.CommandArgument.ToString();
DisplayCandidateDetails();
}
}

content is not allowed between opening and closing tags for element "Button"
So replace your lnkCandidateView button with
<asp:Button ID="lnkCandidateView" ToolTip='<%# Eval("CandiName")%>' Text='<%# Eval("CandiName")%>'
runat="server" Style="text-decoration: none; color: rgb(67, 73, 75);" onmouseover='mouseover(this);'
onmouseout='mouseout(this);' CommandName="View" CommandArgument='<%# Eval("CandidateId")%>' />

Seems like a viewState Issue. One solution is to set the EnableViewState property of GridView to true.
You have set ViewStateMode="Enabled" , so Not sure what's the final setting your GridView is inheriting.May be the ContentPlaceHolder of the masterpage has viewstate
turned off. Try turning it on.

How do I change the forecolor of a control in a .NET Grid View?

How do I access a control in a grid view so that I can change it's forecolor? In this code below, FindControl() returns null.
protected void mileageRowBound(object sender, GridViewRowEventArgs e)
{
(e.Row.Cells[1].FindControl("ddlStateCode") as DropDownList).ForeColor = System.Drawing.Color.LightBlue;
}
I have also tried e.Row.FindControl("ddlStateCode") and a few other variations. I'm stumped.
Someone asked for the markup:
<asp:GridView runat="server" OnPreRender="grvStateWiseMileage_OnPreRender" OnRowCommand="grvStateWiseMileage_OnRowCommand"
CssClass="GridViewStyle" BorderWidth="1" Width="100%" ID="grvStateWiseMileage"
AutoGenerateColumns="false" RowStyle-Height="25px" ShowHeader="false" OnRowDataBound="mileageRowBound">
<Columns>
<asp:TemplateField>
<ItemStyle CssClass="GridViewRowStyle" Width="5%" />
<ItemTemplate>
<asp:Label ID="lblLine" runat="server" onKeyUp="javascript:ValidateDecimal(this)"
Text='<%# Eval("Line#") %>'></asp:Label>
<asp:ImageButton runat="server" ID="imgbtnMileageDelete" ImageUrl="Images/delete.png" />

<ItemTemplate>
<asp:TextBox ID="txtMiles" Style="border: none; border-width: 0px; text-align: right"

onkeydown="return postBackHiddenFieldForEnterMiles(event)"></asp:TextBox>
<cc1:FilteredTextBoxExtender runat="server" FilterMode="ValidChars" FilterType="Custom, Numbers"
ValidChars="." TargetControlID="txtMiles">
</cc1:FilteredTextBoxExtender>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemStyle CssClass="GridViewRowStyle" Width="10%" />
<ItemTemplate>
<asp:DropDownList runat="server" ID="ddlLoadStatus" Style="border: none; border-width: 0px;
width: 100px">
<asp:ListItem Selected="True" Text="Loaded" Value="1"></asp:ListItem>
<asp:ListItem Text="Empty" Value="2"></asp:ListItem>
<asp:ListItem Text="Toll" Value="3"></asp:ListItem>
</asp:DropDownList>
<asp:HiddenField runat="server" ID="hdnMileageType" Value='<% # Eval("LoadStatus")%>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle BorderStyle="None" BackColor="White" />
</asp:GridView>

Try to wrap your line of code in
if(e.Row.RowType == DataControlRowType.DataRow)
{
(e.Row.FindControl("ddlStateCode") as DropDownList).ForeColor = System.Drawing.Color.LightBlue;
}
So it will skip header (and footer and a few others).

I guess the better answer to this question is use CSS to change the color of the control text.
Try add the following lines to the ASPX page.
<style type="text/css">
#ddlStateCode
{
color: #FF0000; /* Change to the hexacode you want */
}
</style>
Hope it helps.
