I have a gridview inside an UpdatePanel (the gridview is showing in a popup). On click of a select button in that grid, I am trying to set a textbox text in the page. But its not working; if I remove the update panel then it will work.
This is my code in aspx:
<div><asp:TextBox ID="txt" runat="server /></div>
<asp:UpdatePanel ID="updLendersearch" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnLenderSearch" EventName="Click" />
</Triggers>
<ContentTemplate>
<div id="divLender" runat="server" class="white_content" style="height: 450px;top: 20%;width: 57%;">
<asp:Label ID="lblBenificiary" runat="server" Text="Beneficiary/Lender :" Font-Names="Candara" ></asp:Label>
<asp:TextBox ID="txtBeneficiaryName" Style="border: 1px solid red" runat="server" Width="80px" CssClass="txtboxes" Font-Names="Candara" ></asp:TextBox>
<asp:RequiredFieldValidator ID="reqBeneficiaryName" runat="server" ErrorMessage="*" ForeColor="Red" ControlToValidate="txtBeneficiaryName" ValidationGroup="lender"></asp:RequiredFieldValidator>
<asp:Label ID="lblLenderState" runat="server" Text="State :" Font-Names="Candara" ></asp:Label>
<asp:DropDownList ID="ddlLenderState" runat="server" AutoPostBack="true" Style="border: 1px solid red"
AppendDataBoundItems="true" CssClass="drpdown" OnSelectedIndexChanged="ddlLenderState_SelectedIndexChanged">
</asp:DropDownList>
<asp:RequiredFieldValidator ID="reqLenderState" runat="server" ErrorMessage="*" ForeColor="Red" ControlToValidate="ddlLenderState" ValidationGroup="lender"></asp:RequiredFieldValidator>
<asp:Label ID="lblLenderCity" runat="server" Text="City :" Font-Names="Candara" ></asp:Label>
<asp:DropDownList ID="ddlLenderCity" runat="server" Width="100px" AutoPostBack="true"
AppendDataBoundItems="true" CssClass="drpdown" OnSelectedIndexChanged="ddlLenderCity_SelectedIndexChanged">
</asp:DropDownList>
<asp:Label ID="lblBeneficiaryZip" runat="server" Text="Zip :" Font-Names="Candara" ></asp:Label>
<asp:DropDownList ID="ddlBeneficiaryZip" runat="server" AppendDataBoundItems="true" Width="100px"
AutoPostBack="true" CssClass="drpdown">
</asp:DropDownList>
<asp:Button ID="btnBenefeciary" ValidationGroup="lender" runat="server" Text="Search" Font-Names="Candara" CssClass="btnBenefeciary" OnClick="btnBenefeciary_Click"/>
<br><br><br><br>
<div>
<asp:GridView ID="grvLenderDetails" CssClass="GridViewStyle" ShowHeaderWhenEmpty="true" OnRowCommand="grvLenderDetails_RowCommand" runat="server" AutoGenerateColumns="false" AutoGenerateSelectButton="true">
<Columns>
.. .. ..
</Columns>
<EmptyDataTemplate>
No Records To Display
</EmptyDataTemplate>
</asp:GridView>
</div>
</div>
<div id="fadeLender" class="black_overlay" runat="server">
<asp:ImageButton ID="imgLenderClose" ImageUrl="../Images/closepnlbtn.png" runat="server"
align="right" Style="margin-right: 140px; margin-top: 78px; border: 0px" OnClick="imgLenderClose_Click" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
If the TextBox is in another UpdatePanel. Make its UpdateMode Conditional which allows you to call its Update method programmatically.
protected void ddlLenderState_SelectedIndexChanged(object sender, GridViewSelectEventArgs e)
{
TxtInfo.Text = "Hello, i'm coming from the GridView.";
UpdInfo.Update();
}
Another approach would be to add an AsyncPostBackTrigger to the outer UpdatePanel with ControlID=grvLenderDetails and EventName=SelectedIndexChanged.
If it's not in an UpdatePanel, then you need to change that. Here are examples:
<asp:UpdatePanel runat="server" ID="UpdInfo" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TxtInfo" runat="server />
</ContentTemplate>
</asp:UpdatePanel>
Here is the trigger approach that does not require you to call Update() from codebehind manually:
<asp:UpdatePanel runat="server" ID="UpdInfo" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TxtInfo" runat="server />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="grvLenderDetails" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Otherwise you'll need to use some sort of JS tricks, e.g.:
ScriptManager.RegisterStartupScript(this, GetType(), "ChangeTextBoxText", "<script type='text/javascript'>$('#"+txt.ClientId+"').val('Hello, i'm from the GridView');</script>", false);

Below is the code which i have applied, it is giving me a error.
<asp:TemplateColumn>
<HeaderTemplate >
<label>Article</label>
</HeaderTemplate>
<ItemTemplate>
<asp:DropDownList ID="DrpArticle" runat="server" TabIndex="4" CssClass="form-control" AutoPostBack="true"
OnSelectedIndexChanged = "DrpArticle_SelectedIndexChanged" AppendDataBoundItems = "true">
</asp:DropDownList>
<asp:UpdatePanel runat="server" ID="UpdatePanel1" UpdateMode="Conditional">
<Triggers><asp:AsyncPostBackTrigger ControlID="DrpArticle" EventName="OnSelectedIndexChanged" /></Triggers>
<ContentTemplate>
<asp:Label ID="LblStock" runat="server" Text="..." ForeColor="#000066"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:TemplateColumn>
A control with ID 'contactButton' could not be found for the trigger in UpdatePanel 'contactUpdatePanel'.
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<asp:UpdatePanel ID="contactUpdatePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:ListView ID="contactList" runat="server">
<ItemTemplate>
<asp:Panel runat="server">
<asp:Label ID="contactLabel" runat="server" Text='<%# Bind("Number") %>' ></asp:Label>
<asp:Button OnClick="contactButton_Click" ID="contactButton" runat="server" Text="Assign"/>
</asp:Panel>
</ItemTemplate>
</asp:ListView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="contactButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
Just remove this line because Listview and button are not outside the update panel so it will work automatically.
<Triggers>
<asp:AsyncPostBackTrigger ControlID="contactButton" EventName="Click" />
</Triggers>
Your final code
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<asp:UpdatePanel ID="contactUpdatePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:ListView ID="contactList" runat="server">
<ItemTemplate>
<asp:Panel runat="server">
<asp:Label ID="contactLabel" runat="server" Text='<%# Bind("Number") %>' ></asp:Label>
<asp:Button OnClick="contactButton_Click" ID="contactButton" runat="server" Text="Assign"/>
</asp:Panel>
</ItemTemplate>
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>

I'm trying to implement UpdatePanels and UpdateProgress controls. I have two UpdatePanels that contain two different DropDownLists (ddlQuestion5IDs and ddlQuestion6IDs).
When I change the selected index of ddlQuestion6IDs, the UpdateProgress loads for both UpdatePanels/DropDownLists. Is this how they normally behave and is there a way of only displaying the corresponding UpdateProgress for each UpdatePanel?
<p>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="Label6" runat="server" Text="Question 5:" Font-Bold="true"></asp:Label>
<br />
<asp:DropDownList ID="ddlQuestion5IDs" runat="server" OnSelectedIndexChanged="ddlQuestion5IDs_SelectedIndexChanged" AutoPostBack="true"></asp:DropDownList>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" DynamicLayout="true">
<ProgressTemplate>
<img src="images/loader.gif" height="20" />
</ProgressTemplate>
</asp:UpdateProgress>
<br />
<asp:Label ID="Label19" runat="server" Text="Question type:" Font-Italic="true"></asp:Label>
