Now as you could see, I have four text box controls two button controls(Save,Search) and one grid and one panel control present in page.

Flow:

 Now as mentioned previously two buttons are save and search.

1.  When User fill up the form and click on Save button data will store into database and after that panel will be popped up describing status message.(done)
2.  Now, while user clicks on Search button grid will appear. (done)
3. Now while user clicks on the delete button, data gets deleted , but that panel is not showing up.(Not Done)
4. After clicking on the delete button I want to reset my controls (textbox) . (Not done)

 

protected void btnSave_OnClick(object sender, EventArgs e)
        {
            pnlMessage.Visible = true;
            _objBelAdministration.flag = "insert";
            _objBelAdministration.strLanguageName = txt_languageName.Text.Trim();
            _objBelAdministration.strCultureName = txt_langCode.Text.Trim();
            _objBelAdministration.strCultureCode = txt_culture_code.Text.Trim();
            _objBelAdministration.strIsoValue = txt_isoValue.Text.Trim();
            if ((_objBlAdministration.InsertLanguageInfo(_objBelAdministration)) > 0)
            {
                lbl_type.Text = "Sucess";
                lblMessage.Text = "Sucessfully inserted into database";
                ScriptManager.RegisterStartupScript(this.Page, typeof(Type), "alert01", "addClassSucess();", true);
            }
            else
            {
                lbl_type.Text = "Failure!";
                lblMessage.Text = "Problem while inserting into database";
                ScriptManager.RegisterStartupScript(this.Page, typeof(Type), "alert012", "addClassDanger();", true);
            }
            GetLanguages();
        }

 

 

 

protected void imgBtnDelLanguage_OnClick(object sender, ImageClickEventArgs e)

        {

            pnlMessage.Visible = true;

            var button = (ImageButton)sender;

            var item = (GridDataItem)(button.NamingContainer);

            _objBelAdministration.flag = "delete";

            _objBelAdministration.autoid = ((Label)(item.FindControl("lblLangAutoId"))).Text;

            if (_objBlAdministration.DeleteLanguageInfo(_objBelAdministration) > 0)

            {

                lbl_type.Text = "Sucess";

                lblMessage.Text = "Deleted from database";

                ScriptManager.RegisterStartupScript(this.Page, typeof(Type), "alert01", "addClassSucess();", true);

            }

            else

            {

                lbl_type.Text = "Error";

                lblMessage.Text = "Error ocured when Deleting from database";

                ScriptManager.RegisterStartupScript(this.Page, typeof(Type), "alert01", "addClassSucess();", true);

            }

            ResetControls();

            GetLanguages();

        }

 

        private void ResetControls()

        {

            txt_languageName.Text = "";

            txt_langCode.Text = "";

            txt_culture_code.Text = "";

            txt_isoValue.Text = "";

        }

Hi Subham,

The remaining issues may be related to AJAX. You can temporarily remove it to achieve the remaining steps from your list:
https://www.telerik.com/support/kb/aspnet-ajax/ajaxmanager/details/get-more-descriptive-errors-by-disabling-ajax

Once the application works as expected, you can turn AJAX back on and add the respective control IDs to the AjaxSettings to resolve this use so that the combo will update and reset the controls accordingly. Also, the radGridLanguage grid should update itself.

I hope this will prove helpful. Please give the provided suggestions a try and let us know about the result.

Eyup
