ArrayList ids = new ArrayList();<br />
        foreach (DataRow DR in dataTable.Rows)<br />
        {<br />
         ids.Add(DR["ID"].ToString());<br />
        }

and use ids arraylist where you want to use.

Hi,

I'm using C# 2.0 and ASP.NET. I have an panel control on my page. I have dynamically created asp:textboxes. But now everything in beneath each other. All my styles have been defined. How do I dynamically add <br /> tages, or a <div> tag? I usually use <div class="VerticalSpacer10"></div> between 2 textboxes for spacing purposes. How do I add this beneath each textbox?

Regards.

you can do like this and add the lt where you want to add BR tag.
LiteralControl lt = new LiteralControl("< br >");

hope it will work

Hi,

I'm not sure what language you are using, but in C# I would do it like this:

string strCountryID = Request.Querystring["CountryID"];
cboCountry.Items.FindByValue(strCountryID).Selected = true;

I hope this helps. If I am wrong please let me know then I will go and investigate.

Regards,
Brendan

Video Streaming

Hi guys,

I'm kinda new to asp.net so I hope to learn something here. I'm now working on a web based video streaming system for a larger e-learning system. My systems goes like this. User A (Teacher) will login into my server through a web site and begin using his/her web cam and upload video files to my server. User B (student)will then login into my server and begin streaming the video from the server to his/her web browser. I've got a solution to the User Bs side, where I'll be embedding the Windows Media Player ActiveX control to stream live media from my server. My question here is, how do i capture video frames from User A and send them to the server?

Thanks a lot

You can't do that in Javascript by default. You can use div layers instead but in this case you no longer using the msg box object.

Do you mean in a "MessageBox" similar to the alert() fn? If so, take a look at the confirm() function... Smile | :)

1. Bind all three keys to the datagrid.

2. In ItemCommand event of datagrid , check for delete command
eg.. switch(e.CommandName)
{
case "Delete":
break;
}

3. In the case "Delete" Find the controls and fetch values from the three key columns if you use a Template column for them in datagrid.
eg. TextBox txt = new TextBox();
txt = (TextBox)e.Item.FindControl("txtKey1");

OR

IF these three key columns are BoundColumn in datagrid then get values using following
eg. e.Item.Cells[3]

4. Once you get all three key values you can delete this record by developing a sql query which will use these values to delete the record.
