Forms Data Controls :: How To Add TemplateField At Runtime
May 11, 2010I want to add one extra Template Field at runtime based on the User-Profile.
View 3 RepliesI want to add one extra Template Field at runtime based on the User-Profile.
View 3 RepliesI have an objectdatasource that accepts 1 parameter and fills a Gridview control.
Above this I have a details view control. Within one of the template fields I have placed a button. I have some code that captures this event.
What I'm trying to do is when a user clicks the button I would like to pass the contents of textbox (also held within the same template field) back into the SQL and refresh the Gridview control.
My ultimate goal is to allow the user to then edit the contents of the Gridview control.
I need the HeaderText of the templatefield to be set dynamically when I bind my grid. I get this error when I try to bind it the same way I would bind a control inside the template:
Databinding expressions are only supported on objects that have a DataBinding event...
I was wondering if anyone could give me an example of how to wire up a binding event for each templatefield in my grid?
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:
protected void Page_Load(object sender, EventArgs e){
for (int i = 0; i < GridView1.Rows.Count; i++)
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

I want to add two image button in the TemplateField.. and add it in the gridview.
I have dynamically created my gridview in the codebehind.
All is working correctly.
I now need to dynamically add a TemplateField to the gridview and populate it with a Button.
I have the following code so far:
TemplateField tempField = new TemplateField();
Button btnRemove = new Button();
I'm creating a new solution to print a grid of my system. I think that is the best solotion, but....I need to copy some TemplateFields between two gridviews, but on the DataBind of the new grid, trows the error "the databind method like eval() only called on context control templatefield". I have Eval() instructions and I can't remove it!.Follows the exactly code:

What I want to do is to replace number with a name. So if in the Month Column it receives five "1" it changes those 5 "1" to JANUARY.
Is it possible? This is because unfortunately I can only arrange my months by number and not by their name, this because of my queries and tables format, so, I thought maybe I can tell the gridview to change the month number to their relative month name.
I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:

In a DetailsView Templatefield i have some binded Labels.
I need to show - hide Templatefield or the detailsView if Label1 is null - empty.
I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

i want to sort a gridview column which is a template field with a repeater control in it. this column has multiple links and i would like to sort using the first link. how can i achieve this.
here is my code:
<asp:TemplateField HeaderText="Groups">
Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!
TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged
Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub
I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.
