Just want to ask how can I find hiddenfield in repeater because my problem I have button and I want to get the associate hiddenfield inside ItemTemplate because I get null value when I try to get hiddenfield value
<asp:Repeater ID="rp_resList" runat="server" OnItemDataBound="rp_resList_ItemDataBound">
<ItemTemplate>
<div class="resourcesResult">
<asp:HiddenField ID="hf_resID" runat="server" Value='<%# Eval("Id") %>' />
<a href='<%# Eval("pageID") %>'><%# Eval("name") %></a>
<br />
<asp:Literal ID="litSummary" runat="server" Text='<%# Eval("summary") %>'></asp:Literal>
<br />
<%-- <asp:Repeater ID="rp_tagsSkill" runat="server">
<ItemTemplate>
<h6>
<%# Eval("Description") %>
</h6>
</ItemTemplate>
</asp:Repeater>--%>
<asp:Repeater ID="rp_tagsTopics" runat="server">
<ItemTemplate>
<h6>
<%# Eval("Description") %>
</h6>
</ItemTemplate>
</asp:Repeater>
<div id="controls">
<asp:ImageButton ID="imgbtnBookmark" runat="server" OnClick="imgbtnBookmark_Click" />
<asp:DropDownList ID="ddlGroup" runat="server" DataSourceID="SqlDS_Groups" DataTextField="name" DataValueField="id" AppendDataBoundItems="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" >
<asp:ListItem Value="-1">Select Group</asp:ListItem>
protected void imgbtnBookmark_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
Bookmark bm = new Bookmark();
HiddenField hiddenField = rptGroup.FindControl("hf_resID") as HiddenField;
bm.UserID =
Guid.Parse(Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey.ToString());
bm.Resoursce.ResourceID = Convert.ToInt32(hiddenField.Value);
Bookmark.Insert(bm);
}
Try this, change you button tag to pass id as CommandArgument value
<asp:ImageButton ID="imgbtnBookmark" runat="server"
OnClick="imgbtnBookmark_Click"
CommandArgument='<%# Eval("Id") %>'/>
in your button click event you can access id using
bm.Resoursce.ResourceID = Convert.ToInt32(e.CommandArgument.ToString());
Change rptGroup.FindControl("hf_resID") as HiddenField; to
e.Item.FindControl("hf_resID")....
I hope this link will help you .
jquery
function showid(dllval) {
var ID = $(dllval).parent().parent().find('[id*="hiddenID"]').val();
alert(ID)
}
asp.net
<asp:DropDownList ID="ddl" runat="server" onclick="showid(this);" >
</asp:DropDownList>
<asp:HiddenField ID="hiddenID" runat="server" Value='<%#Eval("ID")%>' />

I am facing a kind of weird problem.
Problem:
When I click a link button inside a grid view then RowCommand event of a grid view is getting fired when deployed on a localhost but not when deployed on the IIS i.e. client system. I have also tried a link button inside grid view but that's also not getting fired.
Solution: (Temporary)
When I disabled ValidateRequest on the top of the .aspx page. It worked.
What should I do?
So what can be the possible solution for it? I have googled but nothing good came up.

It sounds like your page is trying to submit what it thinks is potentially dangerous content if setting the ValidateRequest = false solves the issue. Is it possible that one of the controls on your page is sending html or something like that?
If one of your controls needs to send HTML then you can overcome this by adding an attribute to your model.
[AllowHtml]
[Required]
public string article_content { get; set; }
This will allow html to be entered into the control.
I need the button inside the datalist to open another page. However the response.redirect does not work !
here is the html
<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">
<div id="content">
<!-- Review -->
<div class="products">
<h3>My Books</h3>
<h4>Items you have purchased</h4>
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"></asp:SqlDataSource>
<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" Width="618px" Height="114px">
<ItemTemplate>
<asp:Label ID="bookid" runat="server" Text='<%# Eval ("BookID") %>' Visible=" false"></asp:Label>
<asp:Label ID="bookname" runat="server" Text='<%# Eval ("Title") %>'></asp:Label>
<asp:Button ID="review" runat="server" Text="Review" CommandName="review" />
</ItemTemplate>
</asp:DataList>
<br />
</div>
</div>
below is the cs file
public void DataList1_ItemCommand(Object source, DataListCommandEventArgs e)
{
if (e.CommandName == "review")
{
DataList1.SelectedIndex = e.Item.ItemIndex;
Label bookid = (Label)DataList1.SelectedItem.FindControl("Bookid");
Response.Redirect("Review.aspx");
}
}
You still need to attach ItemCommand event to DataList1.
<asp:DataList OnItemCommand="DataList1_ItemCommand" ...>
...
</asp:DataList>
Try Server.Transfer("Review.aspx", true);
I have a Repeater which contains Eval commands and a Button (Which I can't access) I would like to access this button and when clicked insert one of the Eval commands (Eg. Car Model) into a listbox I have on the same page.
<asp:Button ID="modelButton" CommandArgument='<%# Eval("Model") %>' Text='<%# "Add Model to List:" + Eval("Model") %>' runat="server" />
<asp:Repeater ID="Repeater2" runat="server" DataSourceID="AccessDataSource1" DataMember="DefaultView" OnItemDataBound="Repeater2_ItemDataBound">
<ItemTemplate>
<div>
<p><img src="carImages/<%#Eval("Artwork")%>" /></div>
<div class="col-xs-4">
<h4><%# Eval("Make")%> (<%# Eval("Year") %>)</h4>
<p><%# Eval("Model")%></p>
<p><%# Eval("Colour")%></p>
<p><%# Eval("Type")%></p>
<div>
<asp:Button ID="modelButton" CommandArgument='<%# Eval("Model") %>' Text='<%# "Add Model to List:" + Eval("Model") %>' runat="server" />
</div>
</a>
</div>
</ItemTemplate>
Just add your oncommand argument to the repeated button
<asp:Button ID="modelButton" CommandArgument='<%# Eval("Model") %>' OnCommand="CommandBtn_Click" Text='<%# "Add Model to List:" + Eval("Model") %>' runat="server" />
you can grab the eval in the behind code
void CommandBtn_Click(Object sender, CommandEventArgs e){
var command = e.CommandArgument;
// Do whatever with it here
}
That will get the evaluated model
I have a DataList inside another DataList. I want to access the child DataList "dlQuestion" events, ItemDataBound event. Also, I'm tring to find the control LableControl "lblQuestion" in the child datalist. How do I do that? Here's the mark-up:
<asp:DataList ID="dlSection" runat="server" Width="100%">
<ItemTemplate>
<div>
<asp:Label ID="lblSection" runat="server" Text='<%# Eval("Section") %>'></asp:Label>
<asp:HiddenField ID="hfSectionId" runat="server" Value='<%# Eval("SectionId") %>' />
</div>
<asp:DataList ID="dlQuestion" runat="server" >
<ItemTemplate>
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Question") %>'></asp:Label></td>
<asp:HiddenField ID="hfQuestionId" runat="server" Value='<%# Eval("QuestionId") %>' />
</ItemTemplate>
</asp:DataList>
</ItemTemplate>
</asp:DataList>
You need to handle ItemDataBound event of the dlQuestion DataList and get lblQuestion Label in that event handler:
Markup:
<asp:DataList ID="dlSection" runat="server" Width="100%">
<ItemTemplate>
<div>
<asp:Label ID="lblSection" runat="server" Text='<%# Eval("Section") %>'></asp:Label>
<asp:HiddenField ID="hfSectionId" runat="server" Value='<%# Eval("SectionId") %>' />
</div>
<asp:DataList ID="dlQuestion" runat="server" OnItemDataBound="dlQuestion_ItemDataBound">
<ItemTemplate>
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Question") %>'></asp:Label></td>
<asp:HiddenField ID="hfQuestionId" runat="server" Value='<%# Eval("QuestionId") %>' />
</ItemTemplate>
</asp:DataList>
</ItemTemplate>
</asp:DataList>
Code-behind:
protected void dlQuestion_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
var lblQuestion = e.Item.FindControl("lblQuestion") as Label;
if (lblQuestion != null)
{
lblQuestion.ForeColor = Color.Red;
}
}
}
This is one way finding label control in child datalist...
//here I am finding item(DataList) of child Datalist
DataList dlSubChild = (DataList)childItem.FindControl("dlSubChild");
foreach (DataListItem subChildItem in dlSubChild.Items)
{
//here I am finding item(TextBox) of sub child Datalist
TextBox txtName = (TextBox)subChildItem.FindControl("txtName");
//set literal(litName) text
litName.Text = string.Format("{0}{1}", "Welcome ", txtName.Text);
}
i hope it will helps you ...
My repeater:
<asp:Repeater ID="rptrContacts" runat="server" OnItemCommand="rptrContact_ItemCommand" >
<div ID="itemTemplate>
<ItemTemplate>
<%# Eval("Name") %>
<%# Eval("Email") %>
<asp:LinkButton ID="lbtnEditContact" runat="server" CommandName="Edit" Text="Edit" CommandArgument='<%# Eval("ContactID") %>' />
<asp:Label ID="lblUpdateConfirm" runat="server" Text="Update Confirmed" Visible="false" />
</ItemTemplate>
</div>
<div ID="editTemplate runat="server" visibility="false">
Update your Info:<br>
Name: <asp:TextBox ID="txtName" runat="server Text="<%# Eval("Name") %>"/> <br>
Email: <asp:TextBox ID="txtEmail" runat="server Text="<%# Eval("Email") %>"/><br>
<asp:LinkButton ID="lbtnUpdateContact" CommandArgument='<%# Eval("ContactID") %>' CommandName="UpdateContact" runat="server" >Update</asp:LinkButton>
</div>
</asp:Repeater
and code for ItemCommand:
switch(e.CommandName)
{
case "Edit":
//make editTemplate div visible
HtmlGenericControl divEditContact = (HtmlGenericControl)e.Item.FindControl ("divEditContact");
divEditContact.Visible = true;
break;
case "Update":
Employee updateEmployee = new Employee
{
employeeName = txtName.Text:
employeeEmail = txtEmail.Text:
}
updateEmployee = API.UpdateEmployee(updateEmployee);
//display lblUpdateConfirm visible to True
// so user sees this confirm messge in the newly updated ItemTemplate
}
How can I access my lblUpdateConfirm and turn its Text state to visible from inside the ItemCommand, so that when the user sees the newly updated ITemTemplate, the label is showing the "Update Confirmed" message?
VB:
CType(e.Item.FindControl("lblUpdateConfirm"), Label).Visible = True;
C #:
Label lblToMakeVisible = (Label)e.Item.FindControl("lblUpdateConfirm");
lblToMakeVisible.Visible = True;
