Hi from France,

I came from old Infragistics software version (7x) and now i'm the last in my society to work on new project with telerik software.

recently i use, splitter,dock and tiles with no problem.

But now I'm using for the first time a grid, a hierachical grid.

before use my sql table (idRubrique,libelle,iOrdre,idRubriqueParent,...)

i prefert test how it's work with simulate datatable, because when i was getting sql table i need to modify data before bind it.

This is my sample to create grid hierarchical content, and i don't know why i don't see my last child (t3) on grid.

If someone can open my eyes ? Thanks ! (excuse me for my bad english)

The code behind: 

Dim t1 As New System.Data.DataTable
        t1.Columns.Add("idRubrique")
        t1.Columns.Add("idRubriqueParent")
        t1.Columns.Add("DEPENSES")
        t1.Columns.Add("BilanAcquisition")
        t1.Columns.Add("ESTIMEES")

        Dim r As Data.DataRow

        r = t1.NewRow
        r.ItemArray = {1, 0, "FONCIER", "TEST", Nothing}
        t1.Rows.Add(r)

        r = t1.NewRow
        r.ItemArray = {2, 0, "VRD", Nothing, Nothing}
        t1.Rows.Add(r)

        Dim t2 As New System.Data.DataTable
        t2.Columns.Add("idRubrique")
        t2.Columns.Add("idRubriqueParent")
        t2.Columns.Add("DEPENSES")
        t2.Columns.Add("BILANACQUISITION")
        t2.Columns.Add("ESTIMEES")

        r = t2.NewRow
        r.ItemArray = {1, 1, "Acquisition", Nothing, Nothing}
        t2.Rows.Add(r)

        r = t2.NewRow
        r.ItemArray = {2, 1, "Frais de Notaire", Nothing, Nothing}
        t2.Rows.Add(r)

        r = t2.NewRow
        r.ItemArray = {3, 1, "Archeologie", Nothing, Nothing}
        t2.Rows.Add(r)

        Dim t3 As New System.Data.DataTable
        t3.Columns.Add("idRubrique")
        t3.Columns.Add("idRubriqueParent")
        t3.Columns.Add("DEPENSES")
        t3.Columns.Add("BILANACQUISITION")
        t3.Columns.Add("ESTIMEES")

        r = t3.NewRow
        r.ItemArray = {1, 1, "Frais liés à la négociation foncière", Nothing, Nothing}
        t3.Rows.Add(r)

        r = t3.NewRow
        r.ItemArray = {2, 1, "Aquisition Terrain", Nothing, Nothing}
        t3.Rows.Add(r)

        r = t3.NewRow
        r.ItemArray = {3, 1, "Commission d'acquisition", Nothing, Nothing}
        t3.Rows.Add(r)

        RadGrid1.MasterTableView.DataSource = t1
        RadGrid1.MasterTableView.DataKeyNames = New String() {"idRubrique"}

        'LV2
        Dim tableViewOrders As New Telerik.Web.UI.GridTableView(RadGrid1)
        tableViewOrders.DataSource = t2
        tableViewOrders.DataKeyNames = New String() {"idRubrique"}

        Dim relationFields As Telerik.Web.UI.GridRelationFields = New Telerik.Web.UI.GridRelationFields()
        relationFields.MasterKeyField = "idRubrique"
        relationFields.DetailKeyField = "idRubriqueParent"
        tableViewOrders.ParentTableRelation.Add(relationFields)
        RadGrid1.MasterTableView.DetailTables.Add(tableViewOrders)

        'LV3
        Dim tableViewOrders2 As New Telerik.Web.UI.GridTableView(RadGrid1)
        tableViewOrders2.DataSource = t3
        tableViewOrders2.DataKeyNames = New String() {"idRubrique"}

        Dim relationFields2 As Telerik.Web.UI.GridRelationFields = New Telerik.Web.UI.GridRelationFields()
        relationFields2.MasterKeyField = "idRubrique"
        relationFields2.DetailKeyField = "idRubriqueParent"
        tableViewOrders2.ParentTableRelation.Add(relationFields2)
        tableViewOrders.DetailTables.Add(tableViewOrders2)

I can't seem to actually catch this exception during run time (debugging with all exceptions turned on), nor do I see any way to ignore/stop that exception from being used. Any ideas?

I have a rad grid inside there are two numeric textbox and if i change the value of numeric text box it will update the other one as per entered valued. I have applied the tabbing on ItemDatabound command like below:


                Dim currentPageeindex As Integer = rgPremiumAllocationPlan.CurrentPageIndex * (e.Item.ItemIndex + 1)
                TryCast(item.FindControl("rtbAllocPercentPAP"), RadNumericTextBox).TabIndex = CShort(currentPageeindex)
                TryCast(item.FindControl("rtbAllocPremiumPAP"), RadNumericTextBox).TabIndex = CShort(currentPageeindex)
                TryCast(item.FindControl("lnkRemove"), LinkButton).TabIndex = CShort(currentPageeindex)


I have applied a blur event on a numeric textbox like below:
 Dim scriptUpdateAmountDue = "updatePremiumAllocationAmountDue(" + Convert.ToString(currentRowIndex) + "," + txtPercentId + "," + txtPremiumId + "," + lnkButtonId + ")"
                rtbAllocPercentPremium.Attributes.Add("onblur ", scriptUpdateAmountDue)

On blur event below javascript funtion updatePremiumAllocationAmountDue is called:
function updatePremiumAllocationAmountDue(currentRowIndex, txtPercentId, txtPremiumAmountId, lnkButtonId) {
    window.ignoreMessage = false;

    if (calledDueToPremiumAllocation == true) {
        calledDueToPremiumAllocation = false;
        return false;
    }

    var rtbAllocPercentPAP = $("input[id$='" + txtPercentId.id + "']");
    var premiumPercent = rtbAllocPercentPAP.val().replace(/,/g, '');

    if (premiumPercent == '') {
        premiumPercent = 0;
        rtbAllocPercentPAP.val(0);
    }
    calledDueToPremiumAllocation = true;
    if (parseFloat(premiumPercent) > 100) {
        alert('Alloc. % value cannot be greater than 100%.');
        rtbAllocPercentPAP.focus();
        calledDueToPremiumAllocation = true;
        return false;
    }
    else {
        $("input[id$='hdnPAPValidate']").val("0");
        if (parseFloat(rtbAllocPercentPAP[0].defaultValue) != parseFloat(premiumPercent)) {
            calledDueToPremiumAllocation = false;


            if (parseFloat(premiumPercent) == parseFloat($("input[id$='hdnAllocPercentValue']").val())) {
                calledDueToPremiumAllocation = false;
                return false;
            }


            $("input[id$='hdnPapRowIndex']").val(currentRowIndex.toString());
            //$("input[id$='hdnAllocPercentValue']").val(rtbAllocPercentPAP.val());

            if ($("input[id$='hdnAllocPercentValue']").val() != "$" && parseFloat(premiumPercent) <= 100) {
                calledDueToPremiumAllocation = false;
                //        var pos2 = 0;
                //        pos2 = premiumPercent.indexOf('.');
                //        if (pos2 > 0) {
                //            pos2 = pos2 + 5;
                //            premiumPercent = premiumPercent.substring(0, pos2);
                //        }

                $("input[id$='hdnAllocPercentValue']").val(premiumPercent);
                $("input[id$='btnAllocPercentPAP']").click();

//                $("input[id$='" + txtPremiumAmountId.id + "']").focus();
//                $("input[id$='rtbAllocPremiumPAP']").focus();
            }


            calledDueToPremiumAllocation = false;
        }
        else {

            validatePremiumAllocationGridAllPercentItems();
        }
    }
}

Now the problem is that when i enter a amount a amout in a textbox and do tab out it focus on next numeric textbox but then auto btn event is called and after completion of this event it get lost. Please refer screent shot 1. In this if i enter value of a row of Alloc. % and do the tab, when the loader apprear on the screen it sets the focus on the corresponding Alloc.Prem but when the postback operation gets completed and loader gets removed the focus gets lost automatically.

Any suggesstion will be helpful.

Sometimes i would like to update control without displaying spinning icon

Is there a way?

 

Thank you

We are going to be moving all of the Telerik controls to lightweight mode and I would like to know if this is supported by all controls. If not is there a list of what is supported.

Hi,

is it possible to make one click (on left pane, tree view) to open containing structure of files on right grid pane  but not expanding the tree on left

and make double click to expand the tree on left pane without listing anything yet on right grid? (something like in window's explorer)

thanks

Hi..
I have a template that I'm generating in code. How do add Vertical and Horizontal scrolling to the bound column?


  boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Title";
            boundColumn.HeaderText = "Department Title";
            boundColumn.UniqueName = "Title";
            boundColumn.ItemStyle.Width = Unit.Pixel(250);
            boundColumn.HeaderStyle.Width = Unit.Pixel(150);
            
            gridActivity.MasterTableView.Columns.Add(boundColumn);

In telerik:RadEditor the below editor tool controls are getting freezed at times and become unusable.

<telerik:EditorToolGroup>
  <telerik:EditorTool Name="FormatBlock" />
  <telerik:EditorTool Name="FontName" />
  <telerik:EditorTool Name="RealFontSize" />
  <telerik:EditorTool Name="Zoom" />
</telerik:EditorToolGroup>

Kindly suggest the solution to get rid of this issue.

Telerik Web UI component version: 2015.1.310.40

I have one scenario where the Telerik RAD gridview has 2 rows.

Gridview having data as like I have mentioned below.
COLUMN1            COLUMN2            COLUMN3          COLUMN4               COLUMN5               COLUMN6
      a                          b                    TEXTBOX1          TEXTBOX2               TEXTBOX3               TEXTBOX4

      a                          b                    TEXTBOX5          TEXTBOX6               TEXTBOX7               TEXTBOX8

COLUMN 3 to COLUMN 6 having texbox where the values are entered by the user
The user enters a value for TEXBOX1, TEXBOX2, TEXBOX3, TEXBOX4, TEXBOX5, TEXBOX6, TEXBOX7, TEXBOX8

COLUMN 1 and COLUMN 2 of ROW 1 and ROW 2 will have the same value as mentioned.

I need to know how to add a new row in the grid if the button is clicked

And the entered value should not get affected. It should be present.
The new row should be added with COLUMN1 and COLUMN 2 having same name as that of the ROW 1 and ROW 2
After clicking on the button the new row should be like below

COLUMN1            COLUMN2            COLUMN3          COLUMN4               COLUMN5               COLUMN6
      a                          b                    TEXTBOX1          TEXTBOX2               TEXTBOX3               TEXTBOX4

      a                          b                    TEXTBOX5          TEXTBOX6               TEXTBOX7               TEXTBOX8

      a                          b                    TEXTBOX9          TEXTBOX10             TEXTBOX11             TEXTBOX12
When the new row is added the user entered value for TEXBOX1, TEXBOX2, TEXBOX3, TEXBOX4, TEXBOX5, TEXBOX6, TEXBOX7, TEXBOX8 should not get changed or should not get changed.

TEXTBOX9, TEXTBOX10, TEXTBOX11, TEXTBOX12 should be empty for entering value.

Even if the user clicks again the button the old rows should not get affected.
I want to know how to code for this in VB.NET since I am using telerik rad gridview
