When disabled viewstate, 'Edit' not working

Hi Sir,

I put the Grid on the usercontrol, I have to set the usercontrol enabledviewstate="false", the problem is now the OnItemCommand="MyGrid_ItemCommand" not fired or not triggered, that means when I click 'Edit' or other commandbutton ,nothing happen, If I set the enabledviewstate = 'true' for the usercontrol, everything works fine, but I need to disable the viewstate for whole usercontrol, do you have some suggetions about this issue? how can I trigger/fire the OnItemCommand event when whole usercontrol 'EnableViewState' is false.
Thanks

Regards

Obtain Data Item from RadGrid

I am in the process of changing from a GridView to a RadGrid and have been experiencing a few issues.

I am attempting to pull an "Active" token from my RadGrid that displays a lot of product information. I do not have the "Active" token being displayed to the user though. It is not set to a hidden value either. The token gets pulled when the user presses the Delete button inside a GridTemplateColumn on my RadGrid.

Before with the GridView, I could use System.Web.UI.DataBinder.Eval(e.Row.DataItem, "Active") and it would return whether or not the Active token was a 1 or a 0.

I currently have the following in VB.NET:

Protected Sub rgvMyGrid_RowCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgvMyGrid.ItemCommand

If (e.CommandName = "DeleteMSDS") Then

Dim myDelete As WinampButton = CType(e.Item.FindControl("btnDelete"), WinampButton)

myDelete.CommandName = "DeleteMSDS"

myDelete.CommandArgument = System.Web.UI.DataBinder.Eval(e.Item.DataItem, "MSDSID")

If System.Web.UI.DataBinder.Eval(e.item.DataItem, "Active")

myDelete.Attributes.Add("onClick", "javascript:return confirm('Are you sure you want to permanently delete this SDS / MSDS?');")

End If

Before this worked like a charm, but I am having trouble. I have noticed that the System.Web.UI.DataBinder(e.Item.DataItem, "MSDSID") never returns anything. And in turn, it cannot find an instance of "Active" being used then.

Grid Cell Colors Moving When Grouping is Used

I am using the "NeedDataSource" method to fill in a grid. On the ItemDataBound I am setting the background colors for some values in a couple of column cells. (Sub below)

This displays properly. Dragging columns around works properly and the colors follow the cells. However, when you do a grouping by dragging the column to the top of the grid the colors do not stay with the cells.

I have attached a before and after image...

Any ideas why this is moving? I am setting the colors based on the FindByUniqueName identifier for the column.

Thanks,
Nathan

Disable or Hide Bad Hyperlink in Grid

I have a grid with a hyperlink to a network folder. The location is constructed in a query based on some information that SHOULD be correct, but there are mistakes made by the end-users and the hyperlink on occasion will be correct.

<telerik:GridTemplateColumn ColumnGroupName="DLB" UniqueName="Location" Display="True" HeaderText="Files" >

<ItemTemplate>

<a href="<%# Eval("Location")%>" target="_blank">Open folder</a>

</ItemTemplate>

</telerik:GridTemplateColumn>

For each row, I would like to somehow handle that hyperlink if the network folder does not exist. Either there will be no link to click or popup a message that informs the user the network folder does not exist.

I figure I would likely use System.IO.Directory.Exists, but I am clueless as to how to implement that. I have made some attempts and searched for a solution, but have not come up with anything that works for me.

Thank you!

Block Element Styling and Mouse Selection in IE

I have noticed a new behavior in the editor in IE while upgrading to the latest version (2014.1.403). If you add certain styles (width, height, float, maybe others) to a block element (div, p, h1, etc), you can no longer select text in that element with the mouse. You can select the element itself, which is displayed with a border and handles, but not the content inside it. The keyboard works fine, but the mouse does not.

You can see this on your demo site. Go to the html tab, modify the opening p tag to include 'width:300px;' in the style, and go back to the design tab. Try to use the mouse to select some text.

The previous version I was using was 2013.2.717. No problem there.

The problem happens in all versions of IE. It seems to work properly in Firefox and Chrome.

[Solved] Cannot set Checked items in RadComboBox in FilterTemplate

I have a radGrid with a FilterTemplate containing a radComboBox with CheckBoxes=true.
I want to preselect a number of items in the radComboBox but that doesn't seem to work inside the filtertemplate (while it works just fine for the radComboBox outside a grid)
The grid columns and template are created in server side code, the data is loaded via a pagemethod.
I minimized my code down to this:

gridtest.aspx.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

using System.Web.Services;

namespace SMTX.Common.Web {

public partial class gridtest : System.Web.UI.Page {

protected void Page_Load(object sender, EventArgs e) {

if (!Page.IsPostBack)

initGrid();

}

public void initGrid() {

Forms.BL.EntityClasses.ViewEntity objView = Forms.BL.MyCode.ViewFactory.fetch(18);

RadGrid1.AllowFilteringByColumn = true;

GridBoundColumn objCol = new GridBoundColumn {

AllowFiltering = true,

DataField = "Field1",

HeaderText = "Field1",

DataType = Type.GetType("System.String"),

FilterTemplate = new FilterTemplateCombo()

};

RadGrid1.Columns.Add(objCol);

objCol = new GridBoundColumn {

AllowFiltering = false,

DataField = "Field2",

HeaderText = "Field2",

DataType = Type.GetType("System.String")

};

RadGrid1.Columns.Add(objCol);

ScriptManager.RegisterStartupScript(this, this.GetType(), "CallGetView", @"setTimeout(function() {radGrid_Init();} , 1000);", true);

}

[WebMethod]

public static List<dataContainer> GetData(List<GridFilterExpression> p_lstFilterExpressions) {

List<dataContainer> lstData = getDataForGrid(p_lstFilterExpressions);

return lstData;

}

public static List<dataContainer> getDataForGrid(List<GridFilterExpression> p_lstFilterExpressions) {

List<dataContainer> lstData = dataContainer.getTestData();

List<String> lstFilterValues = null;

if (p_lstFilterExpressions.Count > 0)

lstFilterValues = p_lstFilterExpressions[0].FieldValue.Split(new []{"||"}, StringSplitOptions.RemoveEmptyEntries).ToList();

if (lstFilterValues == null)

return lstData;

else

return lstData.Where(r => lstFilterValues.Contains(r.Field1)).ToList();

}

public class dataContainer {

public Object Field1 { get; set; }

public Object Field2 { get; set; }

public static List<dataContainer> getTestData() {

List<dataContainer> lstToRetrun = new List<dataContainer>();

lstToRetrun.Add(new dataContainer { Field1 = "Name1", Field2 = "Name1field2" });

lstToRetrun.Add(new dataContainer { Field1 = "Name2", Field2 = "Name2field2" });

return lstToRetrun;

}

public class FilterTemplateCombo : ITemplate {

object m_objDataSource;

public FilterTemplateCombo() {

m_objDataSource = new[] { "Name1", "Name2" };

}

public void InstantiateIn(Control objContainer) {

RadComboBox objCombobox = new RadComboBox();

objContainer.Controls.Add(objCombobox);

objCombobox.DataSource = m_objDataSource;

objCombobox.DataBind();

objCombobox.OnClientItemChecked = "RadGrid_ComboBoxMultiFilterCommand";

objCombobox.CheckBoxes = true;

foreach (RadComboBoxItem objItem in objCombobox.Items)

objItem.Checked = true;

}

var gridTableView = sender.get_parent().get_parent().get_masterTableView();

var arr_objItems = sender.get_checkedItems();

if (arr_objItems.length > 0) {

var strData = "";

for (var i = 0; i < arr_objItems.length; i++)

strData += "||" + arr_objItems[i].get_value();

gridTableView.filter("Field1", strData, Telerik.Web.UI.GridFilterFunction.Custom);

} else {

gridTableView.filter("Field1", "", Telerik.Web.UI.GridFilterFunction.NoFilter);

}

function RadGrid_Update(result) {

var tableView = $find("RadGrid1").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();

}

</script>

</telerik:RadScriptBlock>

</form>

</body>

</html>

I expect the radComboBox filter in Field1 to have it's 2 items checked, but that doesn't seem to be the case, although they were checked in the code.

decrease the opacity of the oval color

Hi,

It is possible to decrease the opacity of the oval color so that some degree of
transparency is maintained even when there are many overlapping ovals? In the
center area of the screenshot below, it’s not possible to see distinct ovals
because the overlapping reaches full opacity very quickly.
