[Solved] get current value in FilterChanging event

Hi,

my name is Patrick and i just bought Telerik Premium Collection for .NET.
I've searched the forums and documentation but could not found any answer for my simple problem;(

So here is my question:
how do i get the FULL value of my Filter in RadGrid?

My Code:

private void rgCustomer_FilterChanging(object sender, GridViewCollectionChangingEventArgs e)

{

if (e.NewItems.Count > 0)

{

FilterDescriptor desc = e.NewItems[0] as FilterDescriptor;

if (desc != null)

{

if (desc.Value.ToString().Length < 3)

e.Cancel = true;

}

The Problem is: desc.Value only returns the current letter i've typed.
Example: if i enter "test" -> desc.Value is "t"

thx for help

[Solved] Remove MultiColumnDropdown when clicking in the dropdown list

Hi,

I search the forum for a solution on this but without finding any answer on it.
I have a multicolumn dropdownlist in my grid.
I use a customized Editor (found in one of the threads here) to show the data.
But when i click on one row, i want the list to disappear and the value to be set in the cell.

And how can i show only the two last columns ( not the ID field) ?
And how can i remove the header row?

Here is the testcode i use:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls.UI;

namespace TestRadGrid

{

public partial class Form1 : Form

List<helper> list = new List<helper>();

list.Add(new helper(1, "test1"));

Cell Group validation

I am creating a small application using the RadGridview for Silverlight which validates whether a group of cells in the same row summ to one. if they do not sum to on then validation for the row fails. I am attempting to set the focus to the first cell of the group which fails validation using the below code:

private void gvRiskMetrics_RowValidating(object sender, Telerik.Windows.Controls.GridViewRowValidatingEventArgs e)

{

RMSectorWeightEnt SectorWeightENT = e.Row.DataContext as RMSectorWeightEnt;

List<double?> GroupSums = checkGroupSums(SectorWeightENT);

int isum = 0;

foreach (double sum in GroupSums)

{

if (sum != 1)

{

GridViewCellValidationResult validationResult = new GridViewCellValidationResult();

validationResult.PropertyName = "Sums";

validationResult.ErrorMessage = "Sum must be equal to 1";

e.ValidationResults.Add(validationResult);

e.IsValid = false;

int Index = gvRiskMetrics.SelectedItems.IndexOf(gvRiskMetrics.SelectedItem);

var item = gvRiskMetrics.Items[Index];

var column = gvRiskMetrics.Columns[m_GroupItemsIndex[isum]];

gvRiskMetrics.ScrollIntoView(item, column);
var cellinfo = new GridViewCellInfo(item, column, gvRiskMetrics);

gvRiskMetrics.CurrentCellInfo = currentCell;
gvRiskMetrics.BeginEdit();

}

isum++;

}

Apparently this won't work since every time the current cell info is updated the the RowValidating event is called and the application essentially goes into an infinite loop. Do you have any suggestions? One other thing here is this behaviour does not occur on the first item in the Gridview collection(Row 1).

Replace Filter Operators

Does the grid support my replacing/removing the Filter operators?

Some column examples:

Total Sales (dollar format)
Replace filter textbox and operators menu with predefined options of "< 1 Million", "1 to 10 Million", "11 to 50 Million", and "> 50 Million".

Category (text but business rules only allow 3 categories)
So replace filter textbox and operators menu with the 3 categories, e.g. "Fruit", "Bread", "Meat"
