In the repeater Design, I have something like this:
Text='<%# Eval("deposit") %>'
How do I insert the value from code-behind to "deposit" not using dataSource but by manually inserting string value?
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:Label ID="lblDeposit" runat="server" Text='<%# Eval("deposit") %>' />
</ItemTemplate>
</asp:Repeater>
You can use ItemDataBound event, to bind field values manually. Like:
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item)
{
Label lbl = e.Item.FindControl("lblDeposit") as Label;
lbl.Text = "You Manual String Value";
}
}
Attach this event to repeater in html markup:
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">

Is it possible to pass the CommandName on my LinkButton to the OnClick event within my GridView in Asp.net Webforms (C#)?
<asp:LinkButton ID="DownloadFile" runat="server" Text="Download" OnClick="OpenModal" CommandArgument='<%# Eval("Customer_ID") %>' CommandName="PassThisName"></asp:LinkButton>
I know it's possible in the RowCommand of the GridView like this:
if (e.CommandName == "PassThisName")
{
}
But I need to get this value in the OnClick event.
It's quite easy, you can do it like this:
Markup
<asp:GridView runat="server" ID="grdCustomer">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="DownloadFile" runat="server" Text="Download" OnClick="DownloadFile_Click" CommandArgument='<%# Eval("Customer_ID") %>' CommandName="PassThisName"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Code Behind
protected void DownloadFile_Click(object sender, EventArgs e)
{
LinkButton lnkDownloadFile = (LinkButton)sender;
string commandName = lnkDownloadFile.CommandName;
}
the following code should show the list of websites in a repeater but it does not (though I get no errors):
In the aspx file I have:
<div>
<asp:Repeater ID="Rpt1" Visible="true" runat="server"></asp:Repeater>
<ItemTemplate>
<asp:HyperLink runat="server" Text = '<%# DataBinder.Eval(Container.GetDataItem(), "Key") %>'
NavigateUrl= '<%#DataBinder.Eval(Container.GetDataItem(), "Value") %>'>
</asp:Hyperlink>
</ItemTemplate>
</div>
In the code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack) return;
CaricaSiti();
}
protected void CaricaSiti()
{
ListDictionary L = new ListDictionary();
L.Add("google", #"http://google.com");
L.Add("microsoft", #"http://microsoft.com");
L.Add("yahoo", #"http://yahoo.com");
Rpt1.DataSource = L;
Rpt1.DataBind();
}
The repeater's ItemTemplate must be inside of the repeater :-)
<asp:Repeater ID="Rpt1" Visible="true" runat="server">
<ItemTemplate>
<asp:HyperLink runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Key") %>'
NavigateUrl= '<%#DataBinder.Eval(Container.DataItem, "Value") %>'>
</asp:Hyperlink>
</ItemTemplate>
</asp:Repeater>
I have this code:
<asp:Repeater id="repeaterCategories" runat="server">
<ItemTemplate>
<div class="categorie-item">
...
<asp:Repeater id="repeaterSubCategories" runat="server">
<ItemTemplate>
...
</ItemTemplate>
</asp:Repeater>
</div>
</ItemTemplate>
</asp:Repeater>
and repeaterSubCategories must be repeaterCategories.SubCategories, for each repeaterCategories. So I have to bind dynamically (for each first repeater iteration) a list of sub categories.
Can I do it? How?
If you have a nested repeater like this:
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<asp:Repeater ID="Repeater2" runat="server"></asp:Repeater>
</ItemTemplate>
</asp:Repeater>
You can use this to bind to it:
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
var data = ((MyClass)e.Item.DataItem).Subcategories;
var repeater2 = (Repeater)e.Item.FindControl("Repeater2");
repeater2.DataSource = data;
repeater2.DataBind();
}
I have a repeater and i have some controls like dropdown and text box how can i catch the drop down selected value and the value entered in the textbox and store them in the hidden field??
It is like a formula Left(c1+c2)*c3 the format is like this.
Repeater Code :
<asp:Repeater ID='myRepeater' runat="server" OnItemDataBound='myRepeater_OnItemDataBound'>
<ItemTemplate>
<asp:HiddenField ID='myHidden' runat="server" />
<asp:DropDownList ID="GeneralDDL" runat="server" AutoPostBack="True" />
</ItemTemplate>
</asp:Repeater>
**Code behind :**
protected void myRepeater_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
var myHidden = (HiddenField)e.Item.FindControl("myHidden");
foreach(RepeaterItem dataItem in 'myRepeater.Items)
{
myHidden.Value = ((DropDownList)'myRepeater.FindControl("GeneralDDL")).SelectedItem.Text;
// Same like for Text box
}
}
Hi have a repeater which is inside a gridview. when i bind the data to gridview the data is binding to the controles inside the gridview but repeater is not binding.
<asp:GridView ID="gvMain" runat="server" AllowPaging="false" AutoGenerateColumns="false"
Width="200px" Height="200px"
onrowdatabound="gvMain_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lbtnDptName" runat="server" Text='<%# Eval("deptName")%>'></asp:LinkButton>
<asp:Label ID="lblDptDesc" runat="server" Text = "sdfsdfsdfdsf"></asp:Label>
<asp:Repeater ID="rtFunctions" runat="server" OnItemDataBound="rtFunctions_ItemDataBound" >
<HeaderTemplate>
<table>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:LinkButton ID="lbtnFunctions" runat="server" ></asp:LinkButton>
<asp:Label ID="lbltemp" Style="border:1px solid blue;width:20px;height:20px;background:green" runat="server" Text="TempLabel" ></asp:Label>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
in Page load:
gvMain.DataSource = objDeptColl;
gvMain.DataBind();
Codebehind for repeater:
protected void gvMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
FunctionCollection objTempFuncColl = new FunctionCollection();
objTempFuncColl = (FunctionCollection)Cache["objFuncColl"];
Repeater rt = (Repeater)e.Row.FindControl("rtFunctions");
if (e.Row.RowType == DataControlRowType.DataRow && objTempFuncColl.Count !=0 )
{
rt.DataSource = objTempFuncColl;
rt.DataBind();
}
}
protected void rtFunctions_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
FunctionCollection objTempFuncColl = new FunctionCollection();
objTempFuncColl = (FunctionCollection)Cache["objFuncColl"];
Repeater rt = (Repeater)e.Item.FindControl("rtFunctions");
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
foreach (Functions f in objTempFuncColl)
{
LinkButton lnk = (LinkButton)e.Item.FindControl("lbtnFunctions");
lnk.Text = f.funcName;
}
}
}
linkbutton in gridview is binding but the linkbutton in repeater is not binding.
The problem appears to be with your repeater ondatabound function.
FunctionCollection objTempFuncColl = new FunctionCollection();
objTempFuncColl = (FunctionCollection)Cache["objFuncColl"];
The first line is not needed as you then replace it with the contents of the cache, which might be null if it's expired or purged or an instance.
For each row in your repeater, the link will be set to the last value in the objtempfunccoll.
you don't really need any of the function apart from lnk.Text = f.funcName; (you'll need to cast f from dataitem)
When you databind to the gridview, ondatabound is called for each row. you've got that wired-up. For each row you now need to find the repeater, set its datasource (we'll call this inner collection) & call databind on the repeater. this will cause ondatabound on the repeater to be called but the container.dataitem now points to each item in the inner collection. We can use that directly, casting container.dataitem to whatever type the inner collection is a list of.
protected void gvMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
FunctionCollection objTempFuncColl = (FunctionCollection)Cache["objFuncColl"];
Repeater rt = (Repeater)e.Row.FindControl("rtFunctions");
if (e.Row.RowType == DataControlRowType.DataRow && objTempFuncColl.Count !=0 )
{
rt.DataSource = objTempFuncColl;
rt.DataBind();
}
}
protected void rtFunctions_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
lnk.Text = ((Functions)e.Item.DataItem).funcName;
}

You do not appear to be binding the repeater within any of this code. You may have some code to bind data to the GridView control, but this will not automatically bind anything to the repeater within the ItemTemplate.
Why don't databind in the aspx, leaving empty the code behind:
<asp:GridView ID="gvMain" runat="server" AllowPaging="false" AutoGenerateColumns="false"
Width="200px" Height="200px">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lbtnDptName" runat="server" Text='<%# Eval("deptName")%>'></asp:LinkButton>
<asp:Label ID="lblDptDesc" runat="server" Text = "sdfsdfsdfdsf"></asp:Label>
<asp:Repeater ID="rtFunctions" runat="server" DataSource='<%# Cache["objFuncColl"] %>' >
<HeaderTemplate>
<table>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:LinkButton ID="lbtnFunctions" runat="server" Text='<%# Eval("funcName") %>' ></asp:LinkButton>
<asp:Label ID="lbltemp" Style="border:1px solid blue;width:20px;height:20px;background:green" runat="server" Text="TempLabel" ></asp:Label>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:TemplateField>
</Columns>
