I've found about 5 articles on how to insert a blank row into a datagrid. I've seen it using footers, using hidden columns, and adding a new row to the DataSource. I am curious of other people have tried the blank row and have found one way works better than another before I start going crazy with coding.
I am also interested in creating multiple blank rows. I have a nested datagrid and one may have the user enter multiple things. The main grid is to enter information about a part. The nested datagrid is to enter multiple subparts.
Thanks!

On my webform a have a datagrid containing bound columns. One of these columns is a status column.
Can anyone tell me how I could display a row of data in bold text (or different background colour) if the bound status column is a specific value?
All rows of data with a different status value must be displayed in non-bold.
Thanks for your assistance.

The samples and discussions on client callback ignores one big issue for me. They all POST to the same page; therefore, there is no speed benefit since all Request, Page, and UserControls/CompositeControls initializations are being called.
I scrapped my ClientCallBack and use XMLHttpRequest instead and redirect the request to a Generic Handler page. I still need to bypass Request event handler by checking if the request is intended for the the ashx page.

Hi,
I have a webForm with 5 treeview controls. They are populated from a data set and they have checkboxes to post their values to another form.
In two of the treeview controls I don’t want to allow multiple selections in the check boxes so I assume that I need client validation the question is how ?
Thanks

Hi there,
+ You can use javascript to scan all the checkboxes of the treeview control based on thier ids to validate.
+ You can persist the current number of the selected checkboxed of the treeview. To do that you might use the client event onclick of the treeview control, you then use javascript to validate this value, you can also persist the value in a hidden field and use the CompareValidator to validate the control.
Just some ideas.

Hello All,
I have created a custom web control. This control contains three different textboxes. I place this control on web form. There is a button on web form. When I click on button, I need to access values of those textboxes. I appreciate if anyone can tell me how to access that value.
Appreciate your help.
Here is the code for Control.
public class MyControl : WebControl
{
private TextBox textbox1 = new TextBox();
private TextBox textbox2 = new TextBox();
private TextBox textbox3 = new TextBox();
[Category("Appearance")]
[DefaultValue("")]
[Localizable(true)]
[Description("This returns value of textboxes as string")]
public string TextBoxChars
{
get
{
this.EnsureChildControls();
return this.textbox1.Text + "-" + this.textbox2.Text + "-" + this.textbox3.Text;
}
}
protected override void Render(HtmlTextWriter output)
{
this.EnsureChildControls();
base.Render(output);
}
protected override void CreateChildControls()
{
this.Controls.Clear();
this.Controls.Add(new LiteralControl(
"<table width='100%' height='100%' " +
"cellpadding='3' cellspacing='3'>"));
this.Controls.Add(new LiteralControl("<tr><td width='100%'>"));
this.Controls.Add(textbox1);
this.Controls.Add(new LiteralControl("</td></tr>"));
this.Controls.Add(new LiteralControl("<tr><td width='100%'>"));
this.Controls.Add(textbox2);
this.Controls.Add(new LiteralControl("</td></tr>"));
this.Controls.Add(new LiteralControl("<tr><td width='100%'>"));
this.Controls.Add(textbox3);
this.Controls.Add(new LiteralControl("</td></tr>"));
this.Controls.Add(new LiteralControl("</Table>"));
}
}

Hi
We have a webapp which the users pull large amounts of data from a remote system. The first user gets hit with the delay as this data is pulled back. It is then caches using Application[dataname] = thisdata. Subsequent requests pull the data from the cache and everybody is happy, and the first user calms down halfway through the morning!
We have had a trace on the data pulled back, and every morning, the same three sets of data are always requested. Is there anyway we can 'pre fill' the Application[] cache with these datasets before anybody hits the app? That's datasets in a loose sense of the term - not real ADO datasets. Sets of data is more correct.
Regards

Hi Angel,
IMO, you should use the Cache object instead of the Application to cache data as it provides you with a couple of ways to specify when you need to refresh the cached data based on the expiration policies or the dependencies. You can read more about this in MSDN:

I have already posted my code can u please read my first posted message..
Thanks and Regards.

You posted an SQL statement.
Show me what your client code looks like which executes this. You must have a web page that sends this query to the database. Show me what code you have already written to attempt to get this to work.

Angel
