You can use the RowDataBound event of the GridView control, and get refetence to the checkbox control at the column 4, you then can enable/disable it.

HI ALL
I want to pass querystring in window.opener.location.reload()

No, you can't do that. The reload method reloads the page using the same URL. If you want to change the URL, assign it to the location property.
Example:
window.opener.location = 'ThePage.aspx?id=42';
---
b { font-weight: normal; }

whenever i am uploading any type of file through WebClient then it working fine but a header message is
adding at the top of the file and also at the end of the file.the header message is like as follows
-----------------------8c8882d5d3c358c
Content-Disposition: form-data; name="file"; filename="P2D Sales Credit Sample.xml"
Content-Type: application/octet-stream
i don't want to have the above header message because whenever i am uploading any picture file then
then this type header causes problem because only for this type of error the gif is not working properly.
suppose whenever i am opening this gif file the the picture is not showing only because of this header.
so pls tell me how could i avoid this header message with sample code.it is very urgent.
my code is
----------
WebClient oclient = new WebClient();
byte[] responseArray = oclient.UploadFile(txtURLToSend.Text,"POST",txtFileToSend.Text);

is it possible to select a row (or multiple rows) by clicking the row header(s) for a datagrid control on client side? i want a java script.
|
|
|

[3.] now when we press DOWN ARROW KEY then next row below to the current row will get selected.

You'll need to write a bit of javascript there as most single keystrokes do not, thankfully, cause a postback to the server.
Try subscribing to the document.onkeyup event. If you determine that the up or down key was hit, force a postback and handle moving the datagrid selecteditemindex on the server. This will not be super fast as you'll postback a lot, but otherwise, I'm not sure how you can set the selecteditemindex in javascript as I believe it is in the viewstate. Try googling on selecteditemindex and javascript to see if you can make it happen w/o the postback.

but i want this only on client side using javascript without postback.
|
|

|

I hear ya. But I'm pretty sure the 'selectedindex' property of the datagrid is in the viewstate, which you are not supposed to mess with on the client manually (1st it's encrypted, 2nd ms says don't do it as they might change the format). Google selectedindex and javascript and datagrid and see what you can come up with.

There was an error message System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object.".
Here is my code. Is there anything wrong? I have already set the PostBackUrl button from the previous page.
<br />
if (!Page.IsPostBack)<br />
{<br />
TextBox t = (TextBox)PreviousPage.FindControl("txtStartDate");<br />
lblStartDate.Text = t.Text;<br />
}<br />

I suppose you don't have txtStartDate textbox on your page, thats why this exception is raised.

i have that textbox obviously. 
thanks in advance. Much appreciated.

In this case, if you really want people to help you to solve this problem, you should copy - paste your code.
if you declare this TextBox in aspx file, then paste it here (at least relevant part), if you create it dynamicaly, paste here code where you do so.
There is a possibility, that problem is with lblStartDate.
Try to debug your application and check each value, you will see if FindControls returns your desired textBox and if lblStartDate is not null.

hi,
i think you are not giving the currect textbox name or textbox is not present
check the textbox name.
thanks

|
|

thanks in advance. Much appreciated.

Hi,
The problem could be, the reference to the page were the textbox(txtStartDate)is available might not be referred. If the textbox has to be referred from the current page were you want the reference you can do so by.
if (!Page.IsPostBack)
{
TextBox t = (TextBox)this.Page.FindControl("txtStartDate");
lblStartDate.Text = t.Text;
}
Hope this should work
Regards
Mohan

I tried and I faced same error.
I should be clearer with the error. It says:
if (!Page.IsPostBack)<br />
{<br />
TextBox t = (TextBox)this.Page.FindControl("txtStartDate");<br />
lblStartDate.Text = t.Text;<br />
}
<big>lblStartDate.Text = t.Text;</big> The error stops at this line saying "Object reference not set to an instance of an object."
The troubleshooting tips were:
Use the "new" keyword to create an object instance.
Check to determine if the object is null before calling the method.
thanks in advance. Much appreciated.

Is that TextBox is inside any other controls like DataGrid,DataList or Panel. The reason for the Problem could be:
1) If the TextBox(txtxStartDate) is not available in the respective page.
2) If the page reference is not set when calling this.Page.FindControl
3) If the TextBox is inside some other controls like DataGrid,DataList or Panel.
Please do check and come around.

I am using MaterPages + .NET 2.0 Login Control.
I observed that if my webform had not used the MasterPages or the webform was not autheticated by the Login Control, the postback will work fine.
Is there a diferent code?
thanks in advance. Much appreciated.
