Trying to access TextBox in a RadGrind and pass it to RadWindow

Hi,

I am trying to access the text box in a radgrid and pass the values of the selected row in the grid with the new value in the textbox to a radwindow which is opened when a button in the same row is clicked.

I am using the following code

aspx:
function ShowDispatchNote(rowIndex, MediaID, ReferenceText) {
   var grid = $find("<%= rgBookoutMedia.ClientID %>");
   var firstDataItem = $find("<%=rgBookoutMedia.ClientID %>").get_masterTableView().get_dataItems()[rowIndex];
   var MediaID = firstDataItem.getDataKeyValue("MediaID");
   var masterTable = grid.get_masterTableView();
   for (var i = 0; i < masterTable.get_dataItems().length; i++) {
   // to access the textbox in each row
   var txtbx = masterTable.get_dataItems()[i].findElement("rtbReference");
   // set alert
   }
   window.radopen("DispatchNote.aspx?MediaID=" + MediaID + "&ReferenceText=" + txtbx.Text, "RadWindow1");
   return false;
   }

cs:
if (e.Item is GridDataItem)
   {
   GridDataItem dataItem = rgBookoutMedia.NamingContainer as GridDataItem;
   Button btnConfirm = (Button)e.Item.FindControl("btnConfirm");
   RadTextBox rtbReference = (RadTextBox)e.Item.FindControl("rtbReference");
   btnConfirm.Attributes["onclick"] = String.Format("return ShowDispatchNote('{0}','{1}');", e.Item.ItemIndex, e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["MediaID"], rtbReference.Text);
   }

I am able to get the value of MediaID as I have specified it as DataKeyNames in the MasterTableView. The other query string ReferenceText shows up as undefined always. How do I get the value of the textbox with new values in the client side before opening the rad window.

The example in http://www.telerik.com/community/code-library/aspnet-ajax/grid/accessing-server-controls-in-a-grid-template-on-the-client.aspx doesn't satisfy my criteria. Can anyone show me a code sample on how to pass the new textbox value to the radwindow.

Thanks

RadSplitter LiveResize causing performance issues. Looking for workaround.

Hi Telerik,

So, I am creating a web portal and it is mainly composed of dynamically created controls. There is a RadSplitter which holds panes which are resizable through the use of the RadSplitBar.

The issue is this: If I have LiveResize turned on -- the user grabs aholds of the RadSplitBar and drags it around. This cause's the client-side OnClientResized event to fire...a lot, I believe. Yet, it looks all normal. No lag or anything after the resize finishes and nothing seems to be hanging. Then, I dynamically create a new control on the page and throw up a loading icon as it generates. The amount of movement of the RadSplitBar seems to be correlated to the amount of time it takes the control to appear on the screen. If LiveResize is off, I see no real issues. If I move the RadSplitBar only a little then the control is created in ~5 seconds. If I grab the RadSplitBar and drag around wildly -- the control never seems to create and the program hangs with a loading panel.

I'm looking for a solution to this as our web dashboard is fairly interactive and it would be nice to see the changes live.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server" >

<script type="text/javascript">

function OnClientResized(pane, args) {

var context = new Object();

var paneIDandHeightandWidth = pane.get_id() + ',' + pane.get_height() + ',' + pane.get_width();

//Context is just thrown away.

CallSetDimensions(paneIDandHeightandWidth, context);

}

function CallbackOnSucceeded(result, context) {

//Logging

}

function CallbackOnFailed(result, context) {

//Logging

}

</script>

</telerik:RadCodeBlock>

The dynamically created RadPane's set their OnClientResized event to this OnClientResized function.

Server-side code:

protected void Page_Load(object sender, EventArgs e)

{

RegisterCallBackReference();

}

private void RegisterCallBackReference()

{

String callBack = Page.ClientScript.GetCallbackEventReference(this, "arg", "CallbackOnSucceeded", "context", "CallbackOnFailed", true);

String clientFunction = "function CallSetDimensions(arg, context){ " + callBack + "; }";

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Call To Server", clientFunction, true);

}

#region ICallbackEventHandler Members

String returnValue;

string ICallbackEventHandler.GetCallbackResult()

{

return returnValue;

}

void ICallbackEventHandler.RaiseCallbackEvent(string eventArgument)

{

bool result = SetDimensions(eventArgument);

if (result)

{

returnValue = "Success.";

}

else

{

returnValue = "Failure.";

}

#endregion

private bool SetDimensions(string args)

{

bool saveSuccessful = false;

string[] paneIDandHeightandWidth = args.Split(',');

string paneID = paneIDandHeightandWidth[0];

int paneHeight = 0;

int.TryParse(paneIDandHeightandWidth[1], out paneHeight);

int paneWidth = 0;

int.TryParse(paneIDandHeightandWidth[2], out paneWidth);

RadPane pane = Utilities.FindControlRecursive(Page, paneID) as RadPane;

if (!object.Equals(pane, null))

{

saveSuccessful = true;

RadPaneSetting paneSetting = RadPaneSetting.GetSettings(pane);

pane.Height = new Unit(paneHeight, UnitType.Pixel);

pane.Width = new Unit(paneWidth, UnitType.Pixel);

controlSave.SavePane(pane);

}

return saveSuccessful;

}

Sorry this code isn't exactly..standard. I need to be able to call SavePane after updating a pane's properties so that Session is aware of the updates. Then, when the page reinitializes I get pane's that maintain their resized-ness.

Does this all make sense? Is there anything I can do here? Something like... detect that more re-sizes have occurred (e.g. the user hasn't let go of the RadSplitBar yet) and only call my event after all the resizing is done? I only need to save the pane state at the end of all the movement.

Cannot find RadUpload.Net2.dll in 2010 Q1

Hi to all.

I'm trying to use the RadProgressArea, but I get an error alert message (attached screen).

I'm going to this help topic http://www.telerik.com/help/aspnet/upload/raduploadprogresshandler.html and I try to follow the instructions, but I'm still having errors, then in the web config (attached screen again). I have the 2010 Q1 version installed of ASP.NET AJAX controls and I only have the Telerik.Web.UI.dll and the Telerik.Web.Design.dll files.

What I have to do?

Thanks in advance and happy new year.

Selecting Last inserted Row, Scrolling into view

I followed the example Selecting Last Inserted Item which seems to work pretty well, but only if I have paging enabled.

If I disable paging and UseStaticHeaders="false" it works.
If I disable paging and UseStaticHeaders="true" it does not work.

Should it be scrolling the item into view with UseStaticHeaders="true"?

What is the best workaround for this, to get the selected item into view when UseStaticHeaders="true"

Thanks in advance

RadFilter Problems

hello,

I am using your control radfilter, and noticed the following problems:

- When I'm working with radfilter, and I select a column of type "bit" and say that it is false, the radgrid is filled with the correct filter, so try to give the true value, it returns an exception and not grid shall bind. By doing so I noticed that a breakpoint that say that the value false he always puts the matter after post put the true value. This bug only happens with columns of type "bit".

- I came across yet another problem when using the provider "RadFilterSqlQueryProvider"to get the sql expression, I noticed that in the cases of columns of type "bit" the provider puts "[ColumnName] = False" instead of putting "[ColumnName ] = 0" or "[ColumnName] = 'False'".

Regards.

internal width of a rad window

I create a rad window with a url loaded in it.

In this window, there is a rad grid with a good width, it looks like 100% the width of the rad window.

When I press the [+] button within the grid to add a record to this grid, it shows the MasterTableViewEditForm template of the grid and now there is a horizontal scroll bar on the rad window. Inside the template, I have a div and a table like this:

   <FormTemplate>
   <div ID="RadGridEditForm" style="padding:5px 5px 5px 5px;">
   <table cellpadding="2" width="100%">
   <tr>
   <td width="80%">

.....

Notice how the table is set to 100%. This causes the grid and hence the radwindow to be much wider than expected and I get a horizontal scroll bar on the radwindow.

If I guess at the width of the table, I can find a value that does not create a scroll bar, but should I have to do this? How can I just set the width to 100% and have it stretch to 100% of the rad window and not something larger? If I remove the width specifier from the table, the table is narrower than the window (only about 2/3rds the way across). I don't see anything else pushing the window that wide, so I don't know why making this table 100% is making the rad window internally wider than it is displaying.

Self-referencing hierarchical grid with pagination at the database level.

I've done quite a bit of searching and cannot find an example of self-referencing hierarchical grid that is paginated at the database level.

For example:

Pull 50 categories from the database (set virtual item count to enable viewing of all pages).
Show an expand button if that category has a parent category.
If expand button is clicked, expand those 50 categories, repeating the same functionality in the above steps to allow categories to be expanded to the Nth level.

The only way I can accomplish this right now is to get a list of ALL categories in the database. This is not very efficient.

Is there any example displaying this?
