i am trying to create a hyperlink field in my gridview from code behind. each link shoudl display the text "Open" and needs to be bound to the column [Request_ID] so that when the link is clicked it will send this request ID. i have created the following code:
[Code]....
[Code]....
and i get the same error. i have a datagrid template class:
[Code]....
In my user control I have gridview, and this grid is created programmatically, using Itemplate. In InstantiateIn methods I have this code.[Code]....
I want to wired up Click event to this LinkButton, and use this event in code behind.This is constructor of GridViewTemplate how implements ITemplate
[Code]....
and i have this call from user control:
[Code]....
where is [Code]....
How do I programmatically bind data to a custom item template column for a GridView? So far, I've done something similar to this:
TemplateField foo = new TemplateField();
foo.ItemTemplate = new bar();
this.GridView1.Columns.Add(foo);
where bar is like this:
[code]....
But ITemplate doesn't contain any kind of data binding properties to implement, and the TemplateField class doesn't seem to have any either...
What do I do?
Edit: The other half is being able to handle the updates to get back to the original datasource. If I just handle the rowupdate events, I don't see my TemplateColumn in the oldvalues/newvalues lists.
i want to create below template field dynamically in C#.net
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chk" runat="server" />
</ItemTemplate>
</asp:TemplateField>
What I want to do is to put a "(reported as invalid)" after the name in the GridView. However, I can't figure out how I can do this, or whether or not I should actually do it in the .aspx file. The field that I am going to check for validity is called invalid, and is a bit. Here's the GridView:
<asp:gridview id="grid" runat="server" datasourceid="sql" autogeneratecolumns="false" useaccessibleheader="true" allowPaging="true" pageSize="10">
<columns>
<asp:BoundField datafield="name" headertext="Name" />
<asp:TemplateField headertext="Link">
<itemtemplate>
<a target="_blank" href="<%# Eval("link") %>"><%# Eval("link") %></a>
</itemtemplate>
</asp:TemplateField>
<asp:BoundField datafield="description" headertext="Description" />
</columns>
</asp:gridview>
My problem i am facing is that i do not know if it's possible to access a single field in my case sold from the following code.
[Code]....
What i want to do is have the checkbox true if the value of sold = yes and false if the value = no I have the checkbox ready on the asp.net side but just need for the checkbox to recognise the datafield, sold, and do and if check statement, is this possible if not i will work around it.
I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
I have a table that has 3 fields (Individual-Id, LastName, and FirstName). I want to create a drop down table that displays both the FirstName and the LastName (example: Smith, John). The field Individual-Id is the 'value' field.
View 4 RepliesI now need to create a Gridview using C# code behind and using PlaceHolder to render in ASPX page. So far everything is Okey, pager and data inside database also can pull out to gridview. But the problem is no sorting function here, below is my code. GridViewTemplate .cs this class is for add data into Gridview ItemTemplate and HeaderTemplate, I modify from here http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.templatefield.templatefield.aspx
public class GridViewTemplate : ITemplate
{
private DataControlRowType templateType;
[code]...
I want to have a control with template supporting so I can put a control on it and I can access them just by their name( just the way Updatepanles do)for instance:
<uc1:FramePanel ID="FramePanel1" runat="server">
<MessageTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"></asp:Button>
</MessageTemplate>
</uc1:FramePanel>
and the in my code could access Button1 like that:
Button1.Text="dsdsdsds";
for now I can access it using find control and Im not happy with it
if you look at updatepanel you can access its control directly
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"></asp:Button>
</ContentTemplate>
</asp:UpdatePanel>
ucan access button1 just easily:
Button1.Text="dsdsdsds";

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

am using an Asp.net web application with C# code and my requirement is to create a Gridview programmatically with Auto generate columns false and i need to add textboxex and dropdown list boxes and Search buttons also in the gridview.
i need to customize the controls of Gridview columns and rows.
I need to create a DataList from code behind.
The structure of that DataList shold be as follows:
<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" RepeatColumns="5" CellPadding="6">
<ItemTemplate>
<table> <tr><td>
<asp:Label ID="lblName" runat="server" ForeColor="Red" Text='<%#Eval("ID") %>'></asp:Label>
</td></tr> </table>
</ItemTemplate>
</asp:DataList>
I have the code below that works fine, but I need to have more than one field using the same command.

I've added an ITemplate to Telerik's RadGrid control called SearchMenuTemplate ala:
[code]...
And the Template class looks something like (mandatory override methods like createchildcontrol have been omitted for brevity):
[ParseChildren(true)]
class searchBar : CompositeControl, INamingContainer
{
public string rbStartsWithText { get; set; }
}
Now, in the source control window the RadGrid control sees the Template. But rbStartsWithText isn't an attribute on the node.
I want to see something like this (note: abs prefix is registered in the markup):
<abs:AbsRadGrid ID="rg" runat="server">
<SearchMenuTemplate rbStartsWithText="Starts With" />
</abs:AbsRadGrid>
Instead rbStartsWithText is throwing a green squiggly and telling me it's not a valid attribute of SearchMenuTemplate.
