Hi,

I am creating columns programmatically based on the data return from database.

For example:

In Datatable i have following rows

ColumnHeader      EditorType
ABC                         TextBox
XYZ                          DropDown
AAA                          TextBox

My Grid display format should be

ABC                               XYZ                                          AAA

Textbox Editor                Dropdown Editor                 Textbox Editor

But i have an error in rgDynamic.Rebind()

Note:

DataBinding of dropdown editor done in ItemCreated event.

protected void rgDynamic_PreRender(object sender, EventArgs e)
{
    if (!rgDynamic.MasterTableView.IsItemInserted)
    {
        foreach (GridDataItem dataItem in rgDynamic.MasterTableView.Items)
        {
            if (dataItem is GridEditableItem)
            {
                dataItem.Edit = true;
            }
        }
    }
    if (rgDynamic.MasterTableView.Items.Count > 0)
        rgDynamic.Rebind();
}

Hi, 

I'm using RadAsyncUpload and when trying to upload a file with more than 206 characters in the filename I'm getting the HTTP error 414 URI too long.

Any idea how to fix this? If not, is there any way to replace the filename of the selected file to the first 140 characters to avoid this error? 

Thanks

on month view the show more events link that goes to day view isn't showing for most days unless I think there is an all day event.

I added this tag but they still don't show

<MonthView VisibleAppointmentsPerDay="2" />

I have created a small sample that demonstrates a problem I am encountering in a much larger project.

The scenario is that I have a RadListView using LayoutTemplate/ItemTemplate and one of the controls in the ItemTemplate is a nested RadListView.  Both lists use NeedDataSource for their data binding and the nested list needs the ID value of the parent list row in order to query for the correct data.  So, in order to make the parent ID available to the child, I have a hiddenfield whose value is ',%# Eval("ID" %> and in the NeedDataSource of the child, I get the parent, do a FindControl on the hidden field and this gives me the ID I need.  If I isolate this in a sample project, it works on initial load, but if I have a need to ReBind the parent list, when the child NeedDataSource executes, it can find the hidden field, but its value is not set.

Here is the full sample code:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="dpCACJTest.ascx.cs"
    Inherits="FACTS_WebApp.DataPanels.dpCACJTest" %>

        {
            StringBuilder sbSQL = new StringBuilder(1000);
            DataTable dtList = new DataTable();
            sbSQL.AppendFormat(@"SELECT 1 as ID
                                    UNION
                                 SELECT 2 as ID
                                    UNION
                                 SELECT 3 as ID");
            dtList = DbHelper.GetDataTable(sbSQL.ToString(), null);
            (sender as RadListView).DataSource = dtList;
        }
        protected void listChild_NeedDataSource(object sender, RadListViewNeedDataSourceEventArgs e)
        {
            StringBuilder sbSQL = new StringBuilder(1000);
            DataTable dtList = new DataTable();
            string ID = "0";
            RadListViewDataItem parentItem = (sender as RadListView).NamingContainer as RadListViewDataItem;
            HiddenField hfID = (HiddenField)parentItem.FindControl("hfID");
            if (hfID.Value != "")
                ID = hfID.Value;
            sbSQL.AppendFormat(@"SELECT '{0}' as ID, 'ID' + '{0}' + 'Value1' as Value
                                    UNION

                                ", ID);

            (sender as RadListView).DataSource = dtList;
        }
        protected void btnRebind_Click(object sender, EventArgs e)
        {
            listParent.Rebind();
        }

On initial load, the results display correctly:

ID     Values
1       ID1Value1
         ID1Value2
2       ID2Value1
         ID2Value2
3       ID3Value1
         ID3Value2

But, if I click the Rebind button and force listParent.ReBind();, then I get the following results:

ID     Values
1       ID0Value1
         ID0Value2
2       ID0Value1
         ID0Value2
3       ID0Value1
         ID0Value2

All the times the listChild_NeedsDataSource fires, the hiddenfield has no value so the string displayed is ID0 rather than ID1, ID2, and ID3.

Any idea on why the difference in behavior between initial load and ReBind()?

Thanks,

Jim

Chrome's latest update version 61 has created a bug in the display of the contextmenu of the radtreeview. 

The scenario occurs when the treeview is the only element on the page and its content is bigger than the window it is in and the browser's native scrollbars are present. When scrolling down to items past the initial set in the viewport the context menu does not appear next to the node you click instead getting stuck at the bottom of the last node that can be seen without scrolling. In my app I have a treeview in a RadWindow but I found the same behavior with a treeview in a standard webform.

I've tested this in the demo example of contextmenu for treeview. The attached project is the same code as the demo and if you run it, expand all the nodes and make the browser window smaller than the treeview content so scrollbars appear, and right click the bottom nodes you will see the context menu not positioned by the node you clicked.

Any ideas for a workaround?

I need to change tooltip width. I found that one way to do it is the following:

.k-chart-tooltip
            {   
                width:500px !important;      
            }

However, that will change tooltip sizes for all charts on the page. Ideally i would like to setup tooltip width from code behind.

Just in case i am providing here my tooltip setup.

Thank you

Hi there guys,

i have this scenario where we have a lot of transactions on the grid that needs to be approved.The grid has a button bound to it for example...

The idea is to create and write each record to csv/excel spreadsheet per record once the approve button is clicked.

is this possible?

kind regards

Marc
