Hi,

I have a problem with my RadGrid. I have a simple RadGrid that is bound to a StoreProcedure this SP takes 4 arguments all of them can be null.

I have bound the DataScourse Select to 4 controls (4 textboxes). The thought here is that the user will enter values into the textboxes and then he press a "search" button and the grid shows the data that the SP gets.

An example would be that the user inputs
1 in the 1st box
nothing in the 2nd box
3 in the 3rd box
nothing in the 4th box

In this case I want it to run the SP with the values (1,null,3,null)
This is all very simple and when I test it in the "ConfigureDataSource"-tutorial that the RadGrid has and I test the query it all works great, I do the same inputs leave 2 and 4 with nothing and inputs 1 and 3 in the others.
But when I then try this "live" it doesn't work, the grid doesn't even load up and give no records nothing happends.

The only thing that I can think of since I've been working with SP before is that I can't simply use a empty textbox or a null i need to use a DBNull.value otherwise the SP won't work. So how can I send in DBNull.value to the SP?

I've tried some things like
BoxNumber.Text = DBNull.value
(BoxNumber is the name of one of the textboxes), but it still doesn't work.

The "search" button simply does a

RadGrid1.DataBind();

And since its bound to the controls I would hope that a empty control would give null, but it doesn't. It seems like a very simply and small problem yet I have been stuck with it for a long time now, please help me out.

Thanks in advance.

I am creating a RadGrid programmatically. It has 2 template columns as well.
When we click Edit button for a row then, one template column has to be changed to a dropdown and other column should be changed to RadListbox of checkboxes.

Also, the ItemTemplate value should be used to select the appropriate checkboxes ni the RadListBox.

I have written the code to select the ListBoxItems of RadListBox, but it doesn't work. Can some help.

The code I have written is of this way:-


In RadGrid's Item Data Bound event:-

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 chkbxDaily = (CheckBox)gdCheckListMaster.Items[i].FindControl("chkbxDaily");
                    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++)
                        {
                            if (int.Parse(gdCheckListMaster.Items[i][gdCheckListMaster.Columns[0]].Text) == int.Parse(ds1.Tables[0].Rows[j]["INTERNALCOMMODITYID"].ToString()))
                            {
                                if (int.Parse(ds1.Tables[0].Rows[j]["DAILY"].ToString()) == 1)
                                {
                                    chkbxDaily.Checked = true;
                                    chkbxDaily.Enabled = false;
                                }
                                if (int.Parse(ds1.Tables[0].Rows[j]["WEEKLY"].ToString()) == 1)
                                {
                                    chkbxWeekly.Enabled = false;
                                    chkbxWeekly.Checked = true;
                                }
                                if (int.Parse(ds1.Tables[0].Rows[j]["YEARLY"].ToString()) == 1)

                                }
                            }
                        }
                    }

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?

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.
