Radgrid Column width problems, please help!!!

Hello,

i want to use RadGrid in asp.net with dynamical columns with different widths. There is no autosizing like autofit. I tried it with javascript. It works but it isnt a good solution. I tried here with some functions, but nothing happens on sizing. Only text will be changed. Visible unvisible is also not working. I think telerik is in grid a very bad solution.

in page:

<telerik:RadGrid ID="rgrdSuche" runat="server" Culture="de-DE" OnColumnCreated="rgrdSuche_ColumnCreated" OnSortCommand="rgrdSuche_SortCommand">
                <MasterTableView AutoGenerateColumns="true" AllowFilteringByColumn="false">

                </MasterTableView>
            </telerik:RadGrid>

i tried with the event itemdatabound, but nothing happened:

protected void rgrdSuche_ItemDataBound(object sender, GridItemEventArgs e)
        {
            try
            {
                if (e.Item is GridHeaderItem)
                {
                    GridHeaderItem headerItem = e.Item as GridHeaderItem;

                    for (int i = 0; i < headerItem.Cells.Count; i++)
                    {
                        switch (headerItem.Cells[i].Text.Replace(" ", ""))
                        {
                            case "Comment":
                                headerItem.Cells[i].Text = "Comment-Text";
                                headerItem.Cells[i].Width = Unit.Pixel(400);
                                break;
                            default:
                                break;
               ...

and event via ColumnCreated will not work also:

protected void rgrdSuche_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
        {
            switch (e.Column.UniqueName)
            {
                case "Comment":
                    e.Column.Visible = false;
                    e.Column.HeaderText = "Comment-Text";
                    e.Column.HeaderStyle.Width = Unit.Pixel(400);
                    e.Column.FilterControlWidth = Unit.Pixel(400);
                 break;

[Solved] Export To Excel from RadGrid

Hi, i'm triying to export to excel from my radgrid from buttons on <commandItemTemplate> tags like this

    
            <MasterTableView CommandItemDisplay="Top" CellSpacing="0" ShowGroupFooter="true" AllowMultiColumnSorting="true" ShowFooter="true" DataKeyNames="NombreTipoCuenta" >                                                                                     
        
                                                    <CommandItemTemplate> 
        
                                                        <asp:ImageButton runat="server" ID="btnExcelExport" ImageUrl="~/images/page_excel.png" OnClick="btnExcelExport_Click" AlternateText="Excel" ToolTip="Excel" />  
        
                                                    </CommandItemTemplate>

but when i click on my button, commanditem hides, and doesn`t work , when i copy this outside the grid it works

When using programmatic binding how do I get a key value

Hi,

I have been trying to use programmatic binding based on the following demo https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/programmatic/defaultcs.aspx but have been having a problem in getting the key value back into the asp.net code behind.

The code is (effectively) the same as the example except I am binding to an entity that has a Guid as a key rather than the EmployeeId in the example and I have added a "delete" button using the following

<telerik:GridButtonColumn UniqueName="DeleteButtonColumn" ButtonType="ImageButton" CommandName="Delete" ConfirmText="Are you sure?" ConfirmDialogType="Classic" ConfirmTitle="Are you sure?" />

I have set up the DataKeyNames and ClientDataKeyNames in the MasterTableView to be DataKeyNames="GUID" and ClientDataKeyNames="GUID"

In the code behind I have added an ItemCommand event that gets called, however

(GridDataItem)e.Item.GetDataKeyValue("GUID") is blank

(GridDataItem)e.Item.KeyValues contains "{GUID:""""}"

Can I use programmatic binding method with a GridButtonColumn with type ImageButton in this way?

[Solved] Radtooltipmanager position problem

Hi there,

"The RadToolTip's designed behavior is to show always in the visible browser area. Therefore, when it should exceed the screen bounds it recalculates its coordinates and reposition."

The above statement is not always true, please see the attached screenshot. When the tooltipmanager showing up, 80% of the time it does the reposition, but sometimes not, the bottom part of the tooltipmanager is hidden from the bottom of the screen, i need to scroll down to see the entire tooltip.

Any suggestions?

Thanks,
Meng

Resize tool crops original width and height

When resizing large images using the imageEditor Resize tool, the width and height being reported in the UI is cropped at 3 characters. So when a large image (eg. 1280x1024) is being resized, the user can get confused.

To repeat this, just visit the online demo: https://demos.telerik.com/aspnet-ajax/imageeditor/examples/resize/defaultcs.aspx

and choose 1280x1024 in the Preset Size drop-down. You'll see that the width and height being reported is '128' and '102' respectively (the ending zeros in both numbers are not visible to the user).
