Hi,

I have a problem with RadDatePicker controls in Asp.Net.

I am dynamically creating 2 RadDatePicker controls at runtime and I want to apply CompareValidator to check if the 'From Date' is less than the 'To Date'. The controls are dynamically created so i have set the AutoPostBack = false. With that the controls are not throwing the validation if i choose the wrong dates.

The condition is:

Date Validation checks - From Date <= To date

Here is my code:

for (int j = 0; j < slistArray.Length; j++)
                {

int counter = 0;

int DateRangeFound = 0;

switch (QuestionType)
                            {

case "DateRange":
                                    if (QuestionName == "DateFrom")
                                    {
                                        RadDatePicker rdpDateFrom = new RadDatePicker();
                                        rdpDateFrom.CssClass = "form-control form-control-item";
                                        rdpDateFrom.ID = "rdpDateFrom" + j.ToString() + "-" + counter;
                                        rdpDateFrom.AutoPostBack = false;
                                        rdpDateFrom.DatePopupButton.Visible = true;
                                        rdpDateFrom.ShowPopupOnFocus = true;
                                        rdpDateFrom.EnableScreenBoundaryDetection = true;
                                        rdpDateFrom.MaxDate = DateTime.Now;

                                        txtC1.Controls.Add(rdpDateFrom);

                                        ++DateRangeFound;
                                    }
                                    else if (QuestionName == "DateTo")
                                    {
                                        RadDatePicker rdpDateTo = new RadDatePicker();
                                        rdpDateTo.CssClass = "form-control form-control-item";
                                        rdpDateTo.ID = "rdpDateTo" + j.ToString() + "-" + (counter - 1);
                                        rdpDateTo.AutoPostBack = false;
                                        rdpDateTo.DatePopupButton.Visible = true;
                                        rdpDateTo.ShowPopupOnFocus = true;
                                        rdpDateTo.EnableScreenBoundaryDetection = true;
                                        rdpDateTo.MaxDate = DateTime.Now;

                                        txtC1.Controls.Add(rdpDateTo);​

                                        ++DateRangeFound;
                                    }
                                    if (DateRangeFound > 1)
                                    {
                                        CompareValidator cvdpDate = new CompareValidator();
                                        cvdpDate.ID = "cvdpDate" + j.ToString() + "-" + counter;
                                        cvdpDate.ControlToCompare = "rdpDateFrom" + j.ToString() + "-" + (counter - 1);
                                        cvdpDate.ControlToValidate = "rdpDateTo" + j.ToString() + "-" + (counter - 1);
                                        cvdpDate.Operator = ValidationCompareOperator.GreaterThanEqual;
                                        cvdpDate.Type = ValidationDataType.Date;
                                        cvdpDate.Text = "*";
                                        cvdpDate.ForeColor = Color.Red;
                                        cvdpDate.ErrorMessage = "End date must be equal or greater than start date - please correct dates.";

                                        txtC1.Controls.Add(cvdpDate);

                                    }
                                    break;

}

panelBody.Controls.Add(txtC1);
                            counter++;

}

 

Any suggestions for the client side jquery validation will also be helpful. 

 

Thank you.

I am currently attempting to add custom nodes to the file explorer view, with the selection of the lowest level of each node displaying the contents of multiple listed directories (create nodes with custom names as their own 'custom trees' where the contents of the corresponding listview would include those of directory1 + 2 + 3 etc.) Here is what I have so far, and I am looking for the equivalent value of the 'viewpath' from the main fileexplorer object for each individual node. 

protected void BindDataTable()
    {
        RadTreeNode temp_node;
        DataTable node_template = CreateDirectoryTable();

        foreach (DataRow row in node_template.Rows)
        {
            temp_node = new RadTreeNode();
            temp_node.Text = (string)row[1];
            temp_node.Value = (string)row[2];

            FileExplorerBase.TreeView.Nodes.Add(temp_node);
        }
    }​

 Is it a simple property in the node object? Because I cannot seem to find it. Or is this functionality present in the treeview object directly?

I have a combo box and a button inside of a EditFormSettings \ FormTemplate.  In the Items_command event of the grid I trap the buitton click event and I'm tryiong to enable or disable it.

Here is the page code

<

 

telerik:RadGrid ID="RadGrid1" runat="server">

 

 

<HeaderContextMenu EnableTheming="True">

 

 

<CollapseAnimation Type="OutQuint" Duration="200">

 

 

</CollapseAnimation>

 

 

</HeaderContextMenu>

 

 

<MasterTableView CommandItemDisplay="Top" DataKeyNames="Contact_ID" Width="100%"

<CollapseAnimation Type="OutQuint" Duration="200">

 

 

</CollapseAnimation>

 

 

</FilterMenu>

 

 

</telerik:RadGrid>

 

and here is the Item_command event in the code behind

 

Private Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

 

 

Dim strCommand As String

 

strCommand = e.CommandName.ToUpper

Select

 

Case strCommand

 

 

    Case Is = "CHANGECOUNTRY"

 

 

       Dim editItem As GridDataItem = CType(e.Item, GridDataItem)

 

       Dim

 

ContactCombo As DropDownList = CType(editItem.FindControl("cboCountry"), DropDownList)

 

        ContactCombo.Enable = "True"

 

    End Select

 

 

End Sub

 

Why is it that I can't get a handle to the combo box ?

Any help would be great !

We have a rad grid.We are binding the grid using datatable and auto generated columns are true.

We want to add all the cell values and display the sum of all the cell values in other column when cell click.

we have tried with row selected event but the sum is not displaying properly when moving from one cell to other.

Please help us to fix the issue.

 

1.       We are
able to fetch the selected cell value but unable to fetch the remaining
corresponding cell values. You can find the same in the sample project
(BatchEdit.aspx – OnBatchEditCellValueChanged event)

 2.       We are
able to fetch the selected cell value and corresponding cell values in the same
row by hardcoding the column names, but dynamically we are unable to get the
values of the cell. You can find the same in the sample project
(OnRowSelected.aspx – OnRowSelected event)

we have used the following code

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>

  <script type="text/javascript">
      function RowSelected(sender, eventArgs) {
          var grid = sender;
          var MasterTable = grid.get_masterTableView();
         
          var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];
          var cell1 = MasterTable.getCellByColumnUniqueName(row, "Value1");
          var cell2 = MasterTable.getCellByColumnUniqueName(row, "Value2");
          var cell3 = MasterTable.getCellByColumnUniqueName(row, "Value3");
          var cell4 = MasterTable.getCellByColumnUniqueName(row, "Value4");
          var total = 0;
          var arr = [];
          var total = 0;
      
          var columnlength = grid.get_masterTableView().get_columns().length;
          for (i = 0 ; i < columnlength; i++) {
              cell = grid.get_masterTableView().get_columns()[i].get_uniqueName();
           
              var cell = MasterTable.getCellByColumnUniqueName(row, cell);
              var val = parseInt(cell.innerText);
              arr[i] = val;
             

          }
          for (i = 1; i < arr.length; i++) {

              total += arr[i];
          }

          var cell1 = MasterTable.getCellByColumnUniqueName(row, "Sum");
          cell1.innerText = total;
          cell1.eventArgs.set_cancel(true);


      }
    </script>

I have the following RadListBox:
     <telerik:RadListBox ID="AttachmentsRadListBox"  CheckBoxes ="true" runat="server" />
it is located in a RadWindow, therefore I am populating it through the following code which is only called when RadWidnow becomes visible:


                AttachmentsRadListBox.DataSource = AttachDT
                AttachmentsRadListBox.DataTextField = "DocumentPath"
                AttachmentsRadListBox.DataValueField = "DocumentID"
                AttachmentsRadListBox.DataBind()
                For Each item As RadListBoxItem In AttachmentsRadListBox.Items
                    item.Checked = True
                Next
So far so good, the RadListBox is populated and all the items are checked.

Now, there is a Save button on the RadWindow when pressed before closing the window I am trying to read the checked items in the AttachmentsRadListBox (Since the user might have changed the status of the checked items). But every effort on reading the items has failed, for example on the Save button click I have the following: 

        Dim test As Integer = AttachmentsRadListBox.Items.Count  // THIS IS ZERO
        For Each item As RadListBoxItem In AttachmentsRadListBox.Items  // THERE ARE NO ITEMS
            If Not item.Checked Then
                Dim DocumentIDToDelete As Integer = item.Value
            End If
        Next
Why is that the last piece of code does not behave as I hope? The AttachmentsRadListBox is not being bounded again through the postback. The only time that it is bounded is when the RadWindow appears. Then the Save button on the RadWindow obviously creates a postback but I don't understand why AttachmentsRadListBox contains no item at that point.

Hi

Is there a equivalent to the $(document).on function for the clientSelectedIndexChanging and clientSelectedIndexChanged events for a RadCombobox in jQuery?

Hi,

I have radgrid with the possibility of adding a line.
One column is of GridDropDownColumn.
How to play the DropDown ??

Thank you.​

We recently updated to the newest version 2015.2.729.40 and our Rotator image onclick doesn't work in Chrome and doesn't work on some machines in IE.

 We had <asp:Image controls in our rotator which are rendered as <mg

 To correct this, we had to change the control type to <asp:ImageButton which renders as <input

  Again, this issue only happened after our recent updated to version 2015.2.729.40

 Simplified example below

I am having a strange problem. First let me start by saying that I am using the Telerik controls supplied by DotNetNuke. So I can not "upgrade" to any other version of the Telerik controls. I am stuck with what I am given.

I wrote a module initially using Telerik v2012.2.724.35 (which was bundled with DNN v6.02.09)and it worked great. I unfortunately am forced to upgrade to a new DNN version because of a bog in Telericks RADSchedule (which effect the month of November only). So...now I am running DNN that comes with Telerik v2013.1.403.40

The problem is that when I click on a button inside the RADGrid and the ItemCommand event fires, previously I was able to obtain the value of each cell in the row that the button was activated in. The *same exact code* running in v2013.1.403.40 of Telerick now returns to me "&nbsp;" for every single cell in the row. It's like the new Telerik version doesn't bind the data to the GridDataItem (e.Item) within the ItemCommand event like it used to.

What am I missing? How do I get the selected row's data like I had before?

I have a HTMLChart that I would like to allow a user to right click on a point on the graph and set a start date and then right click on a second point and set the end date.  After the points are set it would then pass the dates into a stored procedure and update the HTMLChart.  How would I go about doing this?  The chart is currently being populated via server-side code.
