[Solved] Button within RadGrid column

I have a class that inherits from GridBoundColumn (TextFilterButtonColumn.cs) in order to add some custom filtering. I then use TextFilterButtonColumn to create columns within a RadGrid. I would like to add a click event to each item in the column. I've done the following within TextFilterButtonColumn.cs:

public override void Initialize()

{

base.Initialize();

Owner.Page.ClientScript.RegisterClientScriptResource(this.GetType(), "Common.js");

}

public override void PrepareCell(TableCell cell, GridItem item)

{

base.PrepareCell(cell, item);

if (!(item is GridDataItem)) return;

var clickScript = string.Format("javascript:tfbc_Click('{0}','{1}');", this.Owner.ClientID, CommandName);

var linkButton = new HtmlAnchor() { ID = "lnk", InnerText = cell.Text, HRef = clickScript };

cell.Controls.Clear();

cell.Controls.Add(linkButton);

}

In the Common.js file I have the following function:

function tfbc_Click(owner, command, argument) {

$find(owner).fireCommand(command, argument);

}

This click event is then accessed inside of the RadGrid ItemCommand event by setting the CommandName property of the GridBoundColumn to "commandName" and checking for it:

if(e.CommandName == "commandName")

{

var item = (GridDataItem) e.Item;

var strKey = item.GetDataKeyValue("Id").ToString();

var control = (Details)Page.LoadControl("~/Controls/Details.ascx");

control.Id = long.Parse(strKey);

MPS.AddPopup(control);

}

I was hoping to access the Id of the row that the radgrid is bound to by calling GetDataKeyValue however this always returns 1. Is there a way to access information regarding the datasource for that row in the ItemCommand event? Or is there another way to accomplish this? Thanks.

ClientEvents-OnRequestStart and ClientEvents-OnResponseEnd not working

hi

ClientEvents-OnRequestStart and ClientEvents-OnResponseEnd is not working if the controls that i am calling is inside the panel that is disabled and i cannot postback the page using my submit button

For example

ClientEvents-OnRequestStart="ClearNameMsg" ClientEvents-OnResponseEnd="RadManagerResponseEnd"
      function ClearNameMsg() {
                  document.getElementById("<%=CustomDomainTxt.ClientID %>").disabled = true;
                  document.getElementById("<%=SubDomainTxt.ClientID %>").disabled = true;
              }

         function RadManagerResponseEnd() {
                  document.getElementById("<%=CustomDomainTxt.ClientID %>").disabled = false;
                 document.getElementById("<%=SubDomainTxt.ClientID %>").disabled = false;
              }

one of the two textboxes are inside a panel that is disabled. when i click the button submit. I cannot proceed. when i commented out this
       document.getElementById("<%=CustomDomainTxt.ClientID %>").disabled = false;
                 document.getElementById("<%=SubDomainTxt.ClientID %>").disabled = false;
      document.getElementById("<%=CustomDomainTxt.ClientID %>").disabled = true;
                  document.getElementById("<%=SubDomainTxt.ClientID %>").disabled = true;

Everything is working fine again. any help

Preventing Form Submission During File Upload

Is there a graceful way to prevent a form from being submitted while there is a file uploading via RadAsyncUpload? I'm not fond of disabling the submit button or anything of that nature. I'm thinking more along the lines of allowing the submit button to be clicked, and a loading panel displays until the file is finished uploading and the form is submitted. I'm using ajax, so I need to use the AsyncUpload (otherwise I'd just use RadUpload and be done with it). Any suggestions?

Table dialog customization

I would like to customize the InsertTable dropdown tool by removing much of the functionality. I just want the tool to allow users to add a table, and add/delete rows and columns. I want to remove the table wizard and all the formatting capabilities (fonts, sizes, colors, backgrounds, borders, etc.).

I see the dialog code for each of the details (Table Wizard, Table Properties, Cell Properties) but I don't see anywhere that I can change the dropdown. Is that possible?

OK, I made progress on this. The InsertTable item is a button, so there isn't any dialog and it's not a dropdown, so I can't remove child items. I edited the TableWizard dialog, set the whole table to display:none, and added a div above the table with text that says these features are not available. So that meets my immediate need, because all the settings I don't want are in the TableWizard dialog.

So now the question is less urgent, because I have most of a solution. Does anyone know if there's any way to remove the Table Wizard, Table Properties and Cell Properties links from the InsertTable button? It would be better if the user could not make an invalid choice. But this doesn't seem likely to be something I can modify.

how to make the rad panes, spitters adjust according to resolution of the monitor ?

Hi ,

I have implemented a page with multiple rad panes and splitters. The Panes are adjusted according to my monitor resolution. (as it is not accepting the height and width values in terms of percentage)

The issue is..

When it was opened on another screen resolution, everything appears quite ugly.(due to the width and height of the panes)

can you please provide us a solution where the size of the panes should adjust according to the screen of the monitor.

Thanks in advance !,

regards,
Prasad.
