OK, then that's what you need to do. Of course, the paid projects will have better support, but there's some PDF libraries on source forge. If you can't use google, I doubt you'll be able to use a library that doesn't come with good support.

You obviously need to buy a component that converts videos to flv. I don't think that DirectX can be used, but if it can, then you'd still need to buy a filter to do it.

This question has nothing to do with ASP.NET

onserverClick will be called on click event else you have an option to call it by own.So I think when at your home page,you get the data then call it.

Cheers!!

GridView Cell Data....Index Out Of Range Exception

PDTUM21-Jul-09 6:00

Hello,

I am trying to get the data from a cell in a GridView. I am using the following RowCommand event to do this.

protected void GridViewResults_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow gvr = GridViewResults.Rows[Convert.ToInt32(e.CommandArgument)];

string pdf = gvr.Cells[6].Text;

}

An exception is thrown on the first line of code. Debugging this line shows that the code does return the selected row number as the command argument, however, it also returns the following error:

ArguementOutOfRangeException:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

I am confused about which index is returning the error! The only index I am aware of from this line of code is the number of rows in the grid, and that number is returned correctly regardless of the users row selection (as checked in the debugger) and is always non negative. I have been 3 days and all over the Internet trying to get an answer to this. ANY assistance is greatly appreciated.

Thank you for your time, Pat

Try to get the text as below

e.Row.Cells[index].Text

index: it is the cell index and starts from zero

Brij,

Thank you for the quick reply. I applied your code as follows. Below is the complete error message returned:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Source Error:

Line 476: protected void GridViewResults_RowCommand(object sender, GridViewCommandEventArgs e)
Line 477: {
Line 478: string pdf = GridViewResults.Rows[Convert.ToInt32(e.CommandArgument)].Cells[6].Text;

I have also reduced the Cells value to [1] (there are 7 columns) just to make sure that I was not out of the Cell column range. I am a bit surprised that there is no "text overload" as an option as there is in C# desk application. The error is the same. Please let me know if you have any other ideas or if I am applying your code incorrectly. Thank you again for your input. I really need to get this done today.

Best Regards, Pat

Hello Pat

Instead of using

GridViewRow gvr = GridViewResults.Rows[Convert.ToInt32(e.CommandArgument)];

string pdf = gvr.Cells[6].Text;

use

Button button= (Button)e.Row.Cells[0].Controls[0];

as you are having button in column 0.

let me know when done Smile | :)

Hi Brij,

Well, this is one that I have never seen before (perhaps I am leading a sheltered life...?.. Smile | :)

.

OK, I put that in and got this new error:

Compiler Error Message: CS1061: 'System.Web.UI.WebControls.GridViewCommandEventArgs' does not contain a definition for 'Row' and no extension method 'Row' accepting a first argument of type 'System.Web.UI.WebControls.GridViewCommandEventArgs' could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 481: if (e.CommandName.Equals("getPdf"))
Line 482: {
Line 483: Button button = (Button)e.Row.Cells[0].Controls[0];
Line 484:
Line 485:

Could I be missing a using directive for this to compile?. Below is a copy of the using directives for this page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OleDb;
using System.Data;
using System.Diagnostics;

Thanks Brij...Pat
