[Kanat]

Any suggestions ?

I am in stuck !!!

[Princy]

Hello Kanat,

I am not sure about the issue. From your code I can see that you are using both AdvacedDataBinding(attached NeedDataSource) event and in external button click you are using DataBind() method. Plese make the following modification in your code and check whether it works.

C#:

DataTable dt = new DataTable();
  protected void RG_SearchResult_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
  {
     RG_SearchResult.DataSource = dt;
  }
  protected void Btn_Search_Click(object sender, EventArgs e)
  {
     if (RBL_UType.SelectedValue == "0")
       dt = KLIS.Helpers.myConnections.GetDataTableX("udsp_SearchByName", "Sirname", TB_Surname.Text, "Firstname", TB_Name.Text);
     else if (RBL_UType.SelectedValue == "1")
       dt = KLIS.Helpers.myConnections.GetDataTableX("udsp_SearchByFirm", "FirmName", TB_Name.Text);
     RG_SearchResult.Rebind();
  }

Thanks,
Princy.

[Kanat]

I already tried that. not populating grid

even tried 

RG_SearchResult.Dispose();

RG_SearchResult.DataSource = dt;

RG_SearchResult.Rebind();

[Kanat]

Also I tried without OnItemCommand="RG_SearchResult_ItemCommand"

protected void Btn_Search_Click(object sender, EventArgs e)
{

            if (RBL_UType.SelectedValue == "0")
                dt = KLIS.Helpers.myConnections.GetDataTableX("udsp_SearchByName", "Sirname", TB_Surname.Text, "Firstname", TB_Name.Text);
            else if (RBL_UType.SelectedValue == "1")
                dt = KLIS.Helpers.myConnections.GetDataTableX("udsp_SearchByFirm", "FirmName", TB_Name.Text);

            RG_SearchResult.DataSource = dt;
            RG_SearchResult.Rebind();
}

[Kanat]

I checked DataTable, it has records.

I tried

RG_SearchResult.MasterTableView.NoDetailRecordsText = "No data."; 

in Page_Load()

Still showing - "No records to display".

Where to dig ?

[Kanat]

Anybody, please HELP. I tried to call SQL SP in Page_Load(), it works, there are data in GRID, but why after button click it does not work ???

In debug I put breakpoints in Btn_Search_Click and RG_SearchResult_NeedDataSource, cursor reaches them both. But the data is not updated in grid after button click

Is this a really a problem that noone can solve or something wrong with my question ?

[Kanat]

I tried many ways as described in documentation and other examples of community. Cant resolve.

I suppose that my problem is here:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RBL_UType">

                    <telerik:AjaxUpdatedControl ControlID="panelTest_DIV" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RB_Search">

                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGrid1">

            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

May be you can help me ?

plz add this code in your RadAjaxManager.

if u still getting error than temporary remove your RadAjaxManager code part and check Radgrid is bind or not.
if it is rebind than resend your code so i can resend RadAjaxManager code.

Thanks,

RadioButtonList AutoPostBacks, because I need to hide/show some control recording selected Radio. If I remove RadAjaxManager, then it does not show up. I tried to not use RadioButtonList, and select Data in Button click, Ohh, it works.

So, as I supposed, my problem is with - RadAjaxManager

[Schlurk]

The code that you pasted last looks correct in terms of getting the Button to update your RadGrid. Your last statement was confusing though:

"I tried to not use RadioButtonList, and select Data in Button click, Ohh, it works."

Does this mean that you are attempting to use the RadioButtonList in order to get data? It would seem as if the only connection between the RadioButtonList and the RadGrid is the text of the labels. I would double-check that you are properly extracting the information from these labels, and that the function you are calling to retrieve the DataSet that eventually binds to the RadGrid is properly returning the data that you need.

Thank you !!! Finally it works.

Hi, Jayesh

Hope you are still subscribed to this thread yet.

Now I faced another problem. I have a 1 Hierarchcal Table in Grid. There I have 3 columns of link buttons, clicking on them I call Javascript, which pops up a new appropriate page. I traced in debug mode, the code reaches that line, but the page is not poped up. Why ?

Something is blocking it ? In another page, where I use this call to Javascript the page pops up normally. There I use no Rad controls.

protected void RG_SearchResult_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {
            string popupScript;
            string propCode;
            CheckBalanse curBalance = new CheckBalanse();

            if (e.Item.OwnerTableView.Name == "Level2")   //check with name of DetailTableView
            {
              if (e.CommandName == "History")
                {
                    popupScript = "<script language='javascript'>" +
                                    "window.open('History.aspx?code=" + codeStr + "'," +
                                    "'_blank', 'scrollbars=yes, resizable=yes,status=yes," +
                                    "location=yes, toolbar=yes, menubar=yes,top = 0, left = 0, target='_self')" +
                                    "</script>";

                    //ClientScript.RegisterStartupScript(cstype, "???????", popupScript);
                    Page.RegisterStartupScript("History", popupScript);
                }

Hi Kanat,

please check popup blocker status in your browsers.

string fullURL = "window.open('" + "Default.aspx" + "', '_blank', 'height=500,width=800,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes,resizable=no,titlebar=no' );";
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", fullURL, true);

let me know it worked or not.

thanks,
Jayesh Goyani
