Currently the Width of the Edit controls inside the inline Edit form of the Grid can be set only in pixels. In order to be able to implement a responsive layout the developer has to be able to set the width of these controls in percentage.

Have built-in option to do LIKE filtering on grids.

The SearchRow in RadGridView WinForms is extremely good.

How can we implement the same in ASP.Net Ajax RadGrid?

.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource

Steps to reproduce:

• Make any change to the first record, such as modifying the Contact Name.
• On the second record, Click the "x" under the DELETE column to mark it for delete.
• Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())
• Choose to Cancel at the popup prompt.
• Click "Save changes".
• Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.

Grid in BatchEdit mode must be one of the most useful features in some serious industry-level web applications. It comes quite naturally, that the data in the grid must be often extensively validated, and in many cases the client side validation is simply not enough. In our case, we had to use BatchEditing mode and we had to validate user-entered values serverside (due to complex rules, external data to validation against in real time and safety/security of the validation itself). 

Documentation states that BatchEdit does not support ServerSide validation. This makes BatchEdit mode mostly useless for some serious use, which is a pitty. But how much is needed to do so? The only thing we need is, when processing RadGrid_BatchEditCommand, to send the unsaved changes back to the client (overwrite the old values which would come from the database via NeedDataSource) and mark the changed cells as "EDITED" or "CHANGED", because:

a. We have to make sure, that the unsaved rows from the session variable will always come up, next time the user hits the Save changes button, in the BatchEditCommand in Hashtable newValues = command.NewValues; This is because only rows, which RadGrid understand as changed by user-client side, will come up in the newValues HashTable. In case that the user changed, in the first server-side roundtrip, rows 1 and 2, rows 1 and 2 would be saved to the session variable and they would be presented to the user, but in the second round user would not change rows 1 and 2 but change only row 3, it would be only row 3 which would come up in RadGrid1_BatchEditCommand the newValues Hashtable, and we would never get previous, still unsaved, changes

b. in case the user goes to the next page of the grid, using paging arrows in the grid, the grid normally warns about unsaved changes and prevents user from going to the next page, if there are any unsaved changes. If our changed rows from the session are not marked as EDITED, the grid would never ask this and would proceed to the next page, losing users changes.

We were fighting to make this work via some session variables, etc, but then Doncho from Telerik support sent us this simple solution. I think many would be happy if you could add it to the next release, so it is supported out of the box. Attaching files from Doncho, which give an ide to the solution

Thank you.

Good morning,

we have a strange issue using RadGrid with horizontal scroll and frozen columns: there a resizing of the height which gets user experience not the best.

See attached gif.

Could you please help us?

When a big number of items are bound to RadGrid on the server side and Virtualization is enabled paging to the last item is not working as expected.

The problem can be reproduced with the setup in the following demo:

• https://demos.telerik.com/aspnet-ajax/grid/examples/performance/virtualization/defaultcs.aspx 

Increasing the number of Customers bound to the Grid to more than 1000000 leads to the problem.

ResizeGridOnColumnResize is not working the same way when Grid has StaticHeaders.

I want to resize the grid based on the contents and still be able to scroll with headers.

Upon inserting a new record after filtering on the Grid with No records, the exception "No property or field 'Name' exists in type 'DataRowView'" is thrown.

Steps to reproduce:

1. Bind the Grid to an empty data source at initial load
2. Filter any column
3. Insert a new record

Code to replicate the issue:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" AllowFilteringByColumn="true"
    OnNeedDataSource="RadGrid1_NeedDataSource" OnInsertCommand="RadGrid1_InsertCommand">
    <MasterTableView CommandItemDisplay="Top" DataKeyNames="ID">
        <Columns>
            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>
            <telerik:GridButtonColumn CommandName="Delete"></telerik:GridButtonColumn>

            <telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID" ReadOnly="true"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" />

            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name"
                AutoPostBackOnFilter="false" />

            <telerik:GridBoundColumn DataField="Category" HeaderText="Category" UniqueName="Category" DataType="System.String"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" />

            <telerik:GridBoundColumn DataField="Price" HeaderText="Price" UniqueName="Price"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" DataFormatString="{0:C}" />
        </Columns>
        <EditFormSettings InsertCaption="Add New Item" />
    </MasterTableView>
</telerik:RadGrid>

C#

private const string DataTableSessionKey = "RadGridDataTable";
private DataTable SessionDataSource
{
    get
    {
        DataTable dt = Session[DataTableSessionKey] as DataTable;

        if (dt == null || !IsPostBack)
        {
            // Create an empty DataTable with schema defined
            dt = new DataTable();

            dt.Columns.Add("ID", typeof(int));
            dt.Columns.Add("Name", typeof(string));
            dt.Columns.Add("Category", typeof(string));
            dt.Columns.Add("Price", typeof(decimal));

            dt.PrimaryKey = new DataColumn[] { dt.Columns["ID"] };

            Session[DataTableSessionKey] = dt;
        }

        return dt;
    }
}
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    (sender as RadGrid).DataSource = SessionDataSource;
}

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)
{
    GridEditableItem insertItem = (GridEditableItem) e.Item;

    Hashtable newValues = new Hashtable();

    insertItem.ExtractValues(newValues);

    DataRow findLastItem = SessionDataSource.Select("ID=MAX(ID)").FirstOrDefault();

    newValues["ID"] = findLastItem != null ? (int) findLastItem["ID"] + 1 : 0;

    DataRow rowToInsert = SessionDataSource.NewRow();

    foreach (DictionaryEntry entry in newValues)
    {
        rowToInsert[entry.Key.ToString()] = entry.Value ?? DBNull.Value;
    }

    SessionDataSource.Rows.Add(rowToInsert);
}

Currently ExcelML format does not work when both hierarchy and grouping are used.

Time independent filtering (EqualTo problem) is currently not supported with client-side binding in RadGrid, using a WCF with odata  binding.
When i use the filter in a date column, the filter does not return records, it is because is passing date AND TIME to the OData service. 
I have open a support ticket #932463, but Daniel says it is a new feature and not a bug.
So i request it.

When using RadGrid GridDropDownColumn that displays referenced data from a different table allow filter to be replaced with a dropdown of available values. For example if my database has a table called Groups with and Id field and Name field; and it also contains a Members table with a GroupId field which contains the Id from the Groups table when I configure the Members GroupId Field with GridDropDownColumn with ListTextField="Name" ListValueField="Id" DataField="GroupId" as the values for the dropdown I should be able to choose FilterType="DropDownControl" to get the functionality found here http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx for City and Country columns.

RadGrid 508 compliance request for hierarchical grid.

Complex Tables are Missing ID or Headers Attributes

Data tables have multiple logical levels of row or column headers and lack the necessary coding associating the data cells with their respective headers. This issue is a violation of 1194.22(h) in Section 508 and 1.3.1 in WCAG 2.0.

Add id= and headers= attributes to all cells to correctly associate data cells with their respective row and column headers. For further assistance see http://www.hhs.gov/web/policies/webstandards/htmltable.html  and http://webaim.org/techniques/tables/data.

Think it'd be great (and probably pretty easy to do) to have a property on each gridcolumn for ShowFilterTextbox (similar to ShowFilterIcon). 

Right now my workaround is to hide them during ItemCreated or in styling, but it becomes messy, quickly.

RadGrid filtering issue when RenderMode is set to Mobile and the grid is bind on the client

See the movie below:
https://drive.google.com/file/d/0Bzhl0S7bXwuyYlZ1akFwdHZvWDg/view


This can be replicated in the online demo below when edit mode is set to Mobile:
http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/declarative/defaultcs.aspx

In radgrid, the excel style filtering shows a checkbox list of values to filter a column.  This has limited use on a date + time column of a grid, because such a list would show basically every grid row value in the list.  I can bind date only to the filter checkboxes to shorten that list, but if I apply a selected checkbox to filter then there will be no records returned.  This checkbox filtering needs to work with the grid column attribute EnableTimeIndependentFiltering (when it is filtering a datetime column) but it does not - that attribute only works with the datepicker calendar and text entry.
