You need to to do this in the RowCreated event.
Use something like this (adjust to suit):
protected void Grid1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e == null) { throw new ArgumentNullException("e"); }
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[0].ReadOnly = false;
}
}

I have a asp radiobutton on my page and when I display the page it appears that the border for the radiobutton is 50px and the text for the radiobutton is shoved down to the next line. I have the markup for the radiobutton below. When I use a standard HTML radiobutton it appears correctly on the page. See markup below:
Select a button
<asp:radiobutton id="radio2" runat="server" width="20px" text="Milk">
Any help would be great!
Thanks,
Steve

The width that you set here is too less.It must be atleast 50px according to your text.Try with the width as
Width="50px"
Let me know if any doubts.

OK, I moved the radiobutton out of all my div's using css and still get the same thing. The border is still about 50px and the text displays on the next line. when I select the area around the button I can see it's box and the border is wide. ???????

Steve,
If you give your width little bit large it will work fine. I have tested with 50px Its coming properly withput having any issue.
Now, If you have changed the width and still faceing the same problem, then I guess you have some problem with CSS.
See, when you are using RadioButton is aspx page, its renders as follows :
<asp:RadioButton ID="RadioButton1" runat="server" Width="50px" Text="milk" />
Render as :
<span style="display: inline-block; width: 50px;">
<input id="RadioButton1" type="radio" value="RadioButton1" name="RadioButton1"/>
<label for="RadioButton1">milk</label>
</span>
Which may causes the problem. So please check you css for input and label conntrol.
One alternatvie soluation that you can go for is, use Table. Put Radiobutton in one one Cell and data in other cell. Hope you got my point.
Please let me know if you have any issue.
Thanks !
Cheers !

In my css I had a input element with width=200px and when I commented it out it worked. CSS can make your pages great but can also be a pain. Thanks for all of the advice guys.

I am using asp.net 2.0 and ajaxPro in my web application.
1. How can bind my dropdown inside ajaxPro method, without using HtmlTextWriter?
Is it possible?
All the server controls are null inside the ajaxPro method.
2. So, i have created dynamic server controls inside the ajaxPro method and used HtmlTextWriter and rendered in javascript. Here in javascript, i can't able to get this dynamic controls by using getElementId method.
document.getElementId(asp.net control id + "ControlId");
but it returns null.
thanx in advance!
Thanks & Regards,

You can't, databinding is done during page rendering by the ASP.NET engine.
jeneesh k. wrote: All the server controls are null inside the ajaxPro method.
Of course they are. You need to understand the page lifecycle and ajax calls.
Basically, you seem to have no clue about what Ajax is and how to use it. Please do us all, including yourself, a favor and research and understand the technology before trying to use it.

Hi
update panel not working in asp.net 3.5 as it was working in asp.net 2.0.
may be because of I'm not able to make setting for httpHandlers and httpModules in web config in asp.net 3.5.
regards
Hari

What are you talking about? Why can't you make changes to the web.config? It appears you have other problems with your application/environment.

when I put setting on web config:
<system.webServer>
<handlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</handlers>
<modules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</modules>
</system.webServer>
eroor:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

These are not correct for 3.5 project so of course it isn't working.
Version=1.0.61025.0 = ASP.NET 2.0
Version=3.5.0.0 = ASP.NET 3.5
I would suggest you create a new 3.5 project and compare the web.config files

Dear All,
I am doing a scienero where I have dropdownList which is binded to datasource.
I want that based on selectedIndex it should do postback only once.
as for example
If the new SelectedIndex is 1 then it sould do a postback retreive all data from datasource based on selectedIndex. for the 2nd time If I select index 1 then It should not do postback but I want to store items in client side as the first index is selected at some var. and then every time new index is selected it should do postback then save binded items at some var.
any ideas?

tgis is very simple.Did you try something?
Dropdown's selectedindexchanged event is called only you one change the index if selects the same again and again then it is not callled and there is no postback occurs in this scenario.
|
|
|
|
|
thanks for the reply, In fact you are true, but what happens when you first select Index 1 then index 2 then again index 1, I am sure I will do a postback which I dont wanted to do. I would like to store it at some client side variable. any ideas?

When changing the selected Index, fire a javascript function which check whether the selected index is in the list of values stored in hidden variables if it is return false from the Javascript Method.
