Greetings,
My Scenario is as follows,I have a RadCombobox which contains two items
1.Select (value=0)
2.Office(value=1)
On pageload every theing is working fine ie grid is loading when office is selected .The problem is that when combobox item "select" is chosen the grid is again loading.i want to show the grid as null as in the page load.
According to my point of view the problem is NeedDataSource event is not calling except from PageLoad.
Pls help me to solve the issue. Here is my code
private void fill_Grid()
{
clsCheckListMaster chklstmaster = new clsCheckListMaster();
ds = chklstmaster.get_CommodityInInventry(Convert.ToInt32(cmbbxOffice.SelectedValue));
ViewState["ds"] = ds;
if (ds.Tables[0].Rows.Count > 0)
{
gdCheckListMaster.DataSource = ViewState["ds"];
// gdCheckListMaster.DataBind();
}
}
protected void gdCheckListMaster_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
if (cmbbxOffice.SelectedIndex > 0)
{
fill_Grid();
gdCheckListMaster.DataSource =ViewState["ds"];
}
else
{
ViewState["ds"] = null;
}
}
protected void gdCheckListMaster_PreRender(object sender, EventArgs e)
{
if (cmbbxOffice.SelectedIndex > 0)
{
gdCheckListMaster.Rebind();
clsCheckListMaster chklstmaster = new clsCheckListMaster();
for (int i = 0; i < gdCheckListMaster.Items.Count; i++)

CheckBox chkbxWeekly = (CheckBox)gdCheckListMaster.Items[i].FindControl("chkbxWeekly");
CheckBox chkbxYearly = (CheckBox)gdCheckListMaster.Items[i].FindControl("chkbxYearly");
DataSet ds1 = chklstmaster.getDetails_ChklstmsterANDRtlcmdtylst();
if (ds1.Tables[0].Rows.Count > 0)
{
for (int j = 0; j < ds1.Tables[0].Rows.Count; j++)
{

Hi,
I remember that there is a method "SetMaxRequestQueueSize" that we could use to change the queue size of Ajax request.
However, in the latest version (v2010.3.1109.40) of RadAjaxManager, I could not find this method.
How could I change the Max Ajax queue size with the latest RadAjaxManager?
Ping

Hi All,
I have a radchart (having drill-down feature), once user clicks the bars, the 2nd chart gets open with refined data.
My need is that, on click of the 2nd chart's series or seriesItem or legends user need to reach again to top chart.
I know through legends, but how can i tackle when user clicks series/seriesItem.

I read a lot of posts relating to column widths, but i didn't come across what i was looking for. Please forgive me if this is a repost.
I have a problem that can be quite clearly seen in the Scrolling demo here:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/scrolling/defaultcs.aspx
Turn the static headers on and off and watch the sizes of the columns.
When i have the client scrolling + static headers turned on, my grid no longer automatically sizes the columns in a reasonable way. I have a grid with a number of very small columns, and a couple of large descriptive ones. With scrolling and static headers off, it looks great. The big descriptive columns take up the majority of the space, and the smaller columns are allocated almost nothing - tight around the data.
As soon as static headers + scrolling is on, the widths are almost random. The description columns will now only get *slightly* more than others - and none of the columns are tight around the data. When the description fields are shrunk down, they wrap such that each row is now giant - it makes it basically unreadable.
Bottom Line:
Is there any possible way i can do something to maintain the great auto sizing, but still get static headers + scrolling?
-RP
EDIT: i feel like i should probably point out that i cannot hard code my column widths here - not even in percentages. The number of columns being displayed, as well as the data contained within, will vary greatly. The default auto sizing handles that perfectly, but is upset by the static + scroll.

Hi ALL,
I have one treeview on left panel which will bind from database, treeview have N no. of parents and each parent have N no. of childs and each child have N number sub child.
On right side i have one textbox, when user enter some value and if it is one of treenode (Parent/Child/SubChild) then it should be selected..and on that particular selected node i need to fire treeview_nodechange event to bind right side grid.When user try to search text from textbox than treeview may be collapse or expanded, but once page load tree always be collapse.
Parent1
Child11
Child12
Sub Child21
Sub Child22
Sub Child23
Parent2
Child21
Sub Child21
Sub Child22
Child22
Here on page load grid will be collapsed, when user try to search text like "Child11" then Parent1 should be expand and Child11 should be selected.
Same suppose user try to search "Sub Child22" than Parent2 and Child21 should be expand and "Sub Child21" should be selected
And in both case treeview_nodechange event should be fire.
I try this using
RadTreeView1.FindNodeByText(SearchText).Selected := true;
Its running properly for parent node only, while i am trying with any child or sub child node it will give me error and got the node as null.
Please help me on same.
Thanks

Hello guys,
I encounter a very weird problem; I have a page which basically kills my IIS 7.5 (Win7 X32) - requesting it takes very, very long time with a non-ending message "downloading picture nfeswr;t3e4uiowugbhhzfxdcb nvdzf.hgdx .... WebResource.axd blah...blah"; in the end IIS process blocks and I have to restart the service. Requesting the same page from the Visual Studio 2008 development server works fast and without any issues; do you have a clue about what can cause this behaviour?
Thanks,
Cris
