Hi Telerik,

I have a radgrid. When i double click a particular row i get the grid in edit mode.(which i have done using javascript). I am using inplace editmode. I want to update the grid and save the values of the row to the database on button click event. I am using an asp button which is placed outside the grid. I am able to change the value in each cell, but i am not able to read the changed values. I don't have any unique columns. So i have not set datakeyname property. I am using grid template columns in which i have different controls for each column(dropdownlist,checkbox,textbox). Please help me in this regard. Reply me asap.

Thanks in advance,
Priya

Dynamically added RadTreeView not visible

HI

I'm adding a RadTreeView dynamically, then adding some nodes using LoadXmlString.

The Treeview is not visible after loading. But checking the source code, its there in the page, with nodes correctly added, just invisible.

What am I doing wrong?

Here is the creation code
// adding placeholder first recommdended by Telerik
PlaceHolder TVPanel = new PlaceHolder();
this.Form.Controls.Add(TVPanel);

// create a new radtreeview object

RadTreeView Rad1 = new RadTreeView();

Rad1.ID = "Rad1";

Rad1.Visible = true;

TVPanel.Controls.Add(Rad1);

// create a new radtreeview object
RadTreeView Rad1 = new RadTreeView();
Rad1.ID = "Rad1";
Rad1.Visible = true; // doesnt make a difference
TVPanel.Controls.Add(Rad1);

String TreeViewNodes = Navigator_GetContent;
Rad1.LoadXmlString(TreeViewNodes);

PlaceHolder TVPanel = new PlaceHolder();

this.Form.Controls.Add(TVPanel);

// create a new radtreeview object

RadTreeView Rad1 = new RadTreeView();

Rad1.ID = "Rad1";

Rad1.Visible = true;

TVPanel.Controls.Add(Rad1);

// then generate the treeview content

String TreeViewNodes = Navigator_GetContent("Navigate_GetPlaceChecklist.xquery", "");

// attach it

Rad1.LoadXmlString(TreeViewNodes);

PlaceHolder TVPanel = new PlaceHolder();

// adding placeholder first recommdended by Telerik

PlaceHolder TVPanel = new PlaceHolder();

this.Form.Controls.Add(TVPanel);

// create a new radtreeview object

RadTreeView Rad1 = new RadTreeView();

Rad1.ID = "Rad1";

Rad1.Visible = true;

TVPanel.Controls.Add(Rad1);

// then generate the treeview content

String TreeViewNodes = Navigator_GetContent("Navigate_GetPlaceChecklist.xquery", "");

// attach it

Rad1.LoadXmlString(TreeViewNodes);

this.Form.Controls.Add(TVPanel);

// create a new radtreeview object

RadTreeView Rad1 = new RadTreeView();

Rad1.ID = "Rad1";

Rad1.Visible = true;

TVPanel.Controls.Add(Rad1);

// then generate the treeview content

String TreeViewNodes = Navigator_GetContent("Navigate_GetPlaceChecklist.xquery", "");

// attach it

Rad1.LoadXmlString(TreeViewNodes);

// Where String Navigator_GetContent is valid Tree Node text

[Solved] XMLHttpPanel Callback Loading Error...

Hi, I try to use RadXMLHttpPanel to load image for each radgrid row during OnRowSelected client event

RadComboBox client event onload

Hi!

If I want to change the selected item on a RadComboBox at onload (on the client), how can I do that? The real problem is I think is finding a suitable event to call $find in. If I call $find in document.onload it just restuns null.

I have been looking for something similar to the ClientEvents on the RadTextBox but I can't find any thing like it for the RadComboBox.

[Solved] Feature Request: Change default combo text

I really want the ability via a markup property to change the text of "Paragraph Style" and "Apply Css Class". Since most of my content users (sitefinity) are not technical, the terminology for those mean nothing, and if you look at the attached image, the text is cut off anyway (in Firefox at least)

Any change this can be put into PITS? :)

</body>

</html>

It represents an attempt to resize the window when client side code changes the content.

As you'll see if you run the code, clicking on the checkbox opens the Recurrence Editor (from RadScheduler) and the window resizes.

However, I don't seem to be able to get it to revert to the smaller size if the checkbox is unchecked again.

What am I missing?

Radgrid export and ajaxloadingpanel

Hello,

I have an issue using the RadGrid export functions. The RadGrid is placed on a RadAjaxPanel combined with a RadAjaxLoadingPanel. The RadAjaxLoadingPanel is displayed when clicking on the integrated grid export button but it remains open after the file has been downloaded. I would like to not display the RadAjaxLoadingPanel when clicking on export or hide it after download. I tried to hide the RadAjaxLoadingPanel in the onRequestStart method with following code without success:

function onRequestStart(sender, args)

{

if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0 ||

args.get_eventTarget().indexOf("ExportToWordButton") >= 0 ||

args.get_eventTarget().indexOf("ExportToCsvButton") >= 0) {

alert("no ajax");

args.set_enableAjax(false);

currentLoadingPanel = $find("<%= rAJLoadingPanel.ClientID %>");

currentLoadingPanel.hide(currentLoadingPanel);

currentLoadingPanel.style.visibility = 'hidden';

}

Please try the code attached taken from Telerik RadGrid Export samples to reproduce the problem

[Solved] Grid Insert

Hi,
I have an issue, I want to insert a register in a rad grid. When I enable the property ReadOnly="true" I cannot edit the corresponding column which is right (you must not edit your primary key). However this property disables the same fields when I try to insert a new register which (for me) is wrong (I want to insert my primary key in the front-end). How can I set this property in order to maintain it as "ReadOnly" these fields when I'm editing and besides to maintain enabled my pk fields when I insert new fields.
I want to insert 3 primary keys. I don't want to edit it.

Thanks in advance,
William

[Solved] PDF export; hierarchical Rad Grid selected row do not properly out put Master/Detail Table columns without clicking expand column

Hi there,

I am using ASP.Net Ajax 2010, relase Q2 with Vstudio 2008 SP1.

I have a hierarchical Rad Grid, that only the selected Master Table row needs to be exported (i.e. Master row and all related Detail Data).

Attached is my Grid (hierarchy.jpg). If I do not expand the Master Row and click export, it just export Master Row Data (hierarchy export.jpg) not detail table data But If I expand the Master row, and click export it does output Master Detail Data (hierarchy export After Clicking Expand.jpg).

My question is that can I export the Master/Detal related row without expanding the Master Table row? My users will not be happy to expand the row first and later click the export button to export the data. Basically I want the result set will be (hierarchy export After Clicking Expand.jpg) without expanding the Master Table row.

Below is my complete code. Thanks
