Can anybody tell me how I can add ItemTemplate to a Template column in a GridView. What I am doing right now is that I am adding Columns to GridView from code. And now I need to add a Template column with a ItemTemplate.
And my ItemTemplate should contain a label.
I'm trying to programatically reference a FileUpload control which I have within an ItemTemplate. I get a 'Name FileUpload1 is not declared' error message. Code below:
Code is as follows:

I have a GridView with an TemplateField:
<asp:GridView runat="server" ID="gvReport" ondatabinding="gvReport_DataBinding">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("answers") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions") %>' />
</ItemTemplate>
</asp:TemplateField >
</Columns>
</asp:GridView>
What I'd like to do on gvReport_DataBinding is change the field the Evals point to, so I end up with something like:
<asp:Label runat="server" Text='<%#Eval("answers_foo") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions_foo") %>' />
I have gotten this far:
TemplateField tf = ((TemplateField)gvReport.Columns[0]);
But I'm not sure what I should be doing with tf. tf.SomeProperty.Replace("answers", "answers_foo")?
Or am I barking up the wrong airplane on this one?
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.

I have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#
I need to add multiple gridviews to a page displaying different data but of the same structure - the data has a lot of columns and I need it formatting quite tightly - is there a way of creating a template gridview in design mode and then somehow using that however many time I need to in the page as a template.
View 5 RepliesI have a gridview databound to an sql source returning about 1300 records (cars). I have listboxes to narrow the search (model year, manufacturer, segment). What is the most efficient way to tie these listbox selections to the gridview query?
Right now I am piecing together my own sql query string and replacing the SelectCommand. This works, but I keep running into timing issues where the command reverts back to the coded initial value. I can continue debugging this, but is there a better way?

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

I'm trying to add a second command field to an asp.net gridview. Essentially, I want the user to have the options to delete and update records on one page. I've gone through gui's to do this that I have found on the web but none of them work. I think that this is because of the fact that I am working with Visual Studio 2008, so the gui's don't match. Plus, my datasource isn't allowing me to add delete parameters, and update parameters. So, my present goal is to have multiple command fields in my gridview. This would also enable me to add a "duplicate record" functionality, as is needed with this program. I would also like add functionality. If possible. I've been doing all this on multiple screens but I believe I should be able to do this on one screen. Here is my gridview and datasource.

I am trying to add a user control into a div at runtime. I can add the control no probelem but it overwrites the previous control added.Basically, I am trying to add passengers to a travel system - the passenger details are in the user control and I don't know in advance how many there will be. I have an add new passenger button which should append the new user control into the div without overwriting the previous passenger. The code is c#/.net 4. I have tried to save the control data into viewstate and re add it with the new one but that also doesn't work. Here is a snippet of the code I'm using
foreach (Control uc in p_passengers.Controls) {
Passenger p = uc as Passenger;
if (p != null) {
p.SaveValues();
}
}
however, p.SaveAs() (just writes the control values into ViewState) is never hit.

View 4 RepliesI am working with a webdatagrid control. It is fairly simple in that it has Three template columns. Each column contains a separate control; a dropdownlist, webdatepicker and a command button. The webdatagrid is populated using ado.net code and the dropdownlist is populated using a sqldatasource object. I have a command button external to the webdatagrid that I am using to try and add a new row to the webdatagrid. The intention is that a new row will be created at the bottom of the grid that will contain each of the three controls, including having the dropdown populated. I cant seem to find the correct code to do this. I have tried several methods and it has been going on for some time. Can someone tell me if t is possible to do this and if so can they point me in the right direction?
View 8 RepliesI have tried many different combinations to try to get this to work, but I cannot. In the ItemTemplate of a Repeater control, I have a <form> tag. For this third party button to work, each button needs to be surrounded by <form></form> tags. I cannot get the first iteration of the repeater to display the tag, but 2, 3 and beyond, it will. It doesn't make sense to me. Because of this, IE is displaying the page in a funky way.
