getting the RadGrid checkbox column value in server

HI,

I have a RadGrid having a checkbox column, i have added the column as a ItemTemplate to make it editable in the regular mode.

<telerik:GridTemplateColumn UniqueName="IsSelected" DataField="IsSelected">

<ItemTemplate>

<asp:CheckBox ID="chkBoolean" runat="server" Checked='<%# Convert.ToBoolean(Eval("IsSelected")) %>'

Enabled='<%# Convert.ToBoolean(Eval("IsSelectionDisable")) %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

Using this I am able to display a checkbox as editable. Now my problem is how do i get the checked value of the checkox for saving it when the user has changed the checkbox. On click of a button i need to get all the rows that are still checked and save them.

Thanks
Arvind

radeditor not generate its own html

When looking at the Telerik website forums called UI for ASP.NEXT Ajax I have the following questions:
1. it looks like you have an option to have html generated by an asp.net form can either edit your applications' html or not.To be able to have your html edited or not would you show me/tell me how to to set this up? **I would assume this is a web.config file setting
2. Does the radedior generate its own html? IF so, does the radeditor generate the html to fix html errors? If so how can you have the radeditor not generate its own html?

Get formula result from RadSpreadsheet

Hi, there!

I'm trying to get a calculated cell value from a RadSpreadsheet. The documentation says I can use the class FormulaCellValue, but it only works for Worksheets from the Telerik.Windows.Documents.Spreadsheet.Model package, or so it seems, because I use the following code:

Worksheet sheet = RadSpreadsheet1.Sheets[0];

foreach(Row row in sheet.Rows)

{

...

string formula = row.Cells[3].Formula;

Model.FormulaCellValue val = row.Cells[3].Value as Model.FormulaCellValue;

...

}

Here, Worksheet is from the Telerik.Web.Spreadsheet package. The variable formula gets the text of the formula right, but val is null. The cell is showing the result correctly on the spreadsheet. What is wrong here?

Thank you!

Access other control in inputbox

Dear all,

I have a radgrid like follows:

<telerik:RadGrid ID="uiGrid" runat="server"
AutoGenerateColumns="false" ItemStyle-BackColor="White" AlternatingItemStyle-BackColor="White"
OnDataBound="uiGrid_DataBound" OnItemDataBound="uiGrid_ItemDataBound" OnNeedDataSource="uiGrid_NeedDataSource"
ClientSettings-ClientEvents-OnKeyPress="keyPressInGrid"
Width="100%" Height="500">
<ClientSettings>
<Scrolling CountGroupSplitterColumnAsFrozen="false" AllowScroll="true" UseStaticHeaders="True" SaveScrollPosition="true" FrozenColumnsCount="3"></Scrolling>

</ClientSettings>
<MasterTableView>
<GroupByExpressions>
<telerik:GridGroupByExpression>
<SelectFields>
<telerik:GridGroupByField FieldAlias="<%$ Resources:Resource,Group %>" FieldName="IndicatorParentName"></telerik:GridGroupByField>
</SelectFields>
<GroupByFields>
<telerik:GridGroupByField FieldName="IndicatorParentName" SortOrder="Ascending"></telerik:GridGroupByField>
</GroupByFields>
</telerik:GridGroupByExpression>
</GroupByExpressions>
<Columns>
<telerik:GridBoundColumn DataField="IndicatorName" HeaderText="<%$ Resources:Resource,Indicator %>" UniqueName="IndicatorName"
SortExpression="IndicatorName" DataType="System.String" ItemStyle-Wrap="false">
</telerik:GridBoundColumn>
<telerik:GridTemplateColumn>
<ItemTemplate>
<asp:HiddenField ID="uiIndicatorID" runat="server" Value='<%#Eval("IndicatorID")%>' />
<asp:HiddenField ID="uiIndicatorName" runat="server" Value='<%#Eval("IndicatorName")%>' />
<asp:ImageButton ID="uiTipsButton" runat="server" ImageUrl="images/information-icon.png?20170703" Width="16" Height="16" />
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="<%$ Resources:Resource,Unit %>">
<ItemTemplate>
<asp:Label ID="uiUnit" runat="server" />
</ItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>

And I have functions to find controls value like this :

foreach (GridDataItem item in uiGrid.MasterTableView.Items)
{
if (item.ItemType == GridItemType.Item || item.ItemType == GridItemType.AlternatingItem)
{
HiddenField uiIndicatorID = item.FindControl("uiIndicatorID") as HiddenField;
for (int i = 0; i < uiGrid.MasterTableView.Columns.Count; i++)
{
HiddenField uiLocationID = item.FindControl("uiID_" + i.ToString()) as HiddenField;
RadNumericTextBox uiCurrencyBox = item.FindControl("uiCurrencyBox_" + i.ToString()) as RadNumericTextBox;
RadNumericTextBox uiInputBox = item.FindControl("uiInputBox_" + i.ToString()) as RadNumericTextBox;
HiddenField uiRemarksBox = item.FindControl("uiRemarksBox_" + i.ToString()) as HiddenField;

Now I want is not to loop the GridIitem to do the processing, I want to do the processing when user leave each inputbox (inside the grid) event happened. So I added the follows , in the InstantiateIn I add a delegation txt_TextChanged to the TextChanged event of _inputbox.

public void InstantiateIn(System.Web.UI.Control container)

_inputBox = new RadNumericTextBox();
_inputBox.ID = "uiInputBox_" + _controlIDNumber;
_inputBox.Width = Unit.Pixel(100);

UsageEdit ue = new UsageEdit(); //UsageEdit is another class
_inputBox.TextChanged += ue.txt_TextChanged;

So in UsageEdit Class, I have the function

public void txt_TextChanged(object sender, EventArgs e)
{

}

My question is, how can I get the control value in function. like something:

public void txt_TextChanged(object sender, EventArgs e)
{

HiddenField uiIndicatorID = sender.FindControl("uiIndicatorID") as HiddenField;
for (int i = 0; i < uiGrid.MasterTableView.Columns.Count; i++)
{
HiddenField uiLocationID = sender.FindControl("uiID_" + i.ToString()) as HiddenField;
RadNumericTextBox uiCurrencyBox = sender.FindControl("uiCurrencyBox_" + i.ToString()) as RadNumericTextBox;
RadNumericTextBox uiInputBox = sender.FindControl("uiInputBox_" + i.ToString()) as RadNumericTextBox;
HiddenField uiRemarksBox = sender.FindControl("uiRemarksBox_" + i.ToString()) as HiddenField;
}

Can I do that, can I access the control of the grid item in leave event of the inputbox that is in the grid item?

How disable client-side filtering in RadGrid?

Hello

It seems by default, RadGrid applies client-side filtering on columns. When I press enter on a column, I can see at the end, client side filter is being applied. Is there any property to disable it? Here is a sample:

<telerik:RadGrid AutoGenerateColumns="False" ID="grdInProgressTasks" runat="server" Width="100%" AllowMultiRowSelection="true" AllowSorting="true"

AllowPaging="true" OnNeedDataSource="grdInProgressTasks_NeedDataSource" CssClass="grdTasks pro-responsive" OnItemDataBound="GrdInProgressTasks_ItemDataBound"

OnItemCommand="grdInProgressTasks_ItemCommand">

<MasterTableView DataKeyNames="CrmObjectId,ProcessInstanceTypeIndex,Description, ColorR,ColorG,ColorB" ClientDataKeyNames="Id,CrmObjectId,ProcessInstanceTypeIndex" AllowCustomPaging="true" AllowFilteringByColumn="true" >

<Columns>

<septa:LocalizedBoundColumn DataField="DSenderId" HeaderResourceKey="General.Literal.AssignedFrom" />

<septa:LocalizedBoundColumn DataField="CrmObjectSubject" HeaderResourceKey="General.Literal.General_Subject" />

<septa:LocalizedTemplateColumn DataField="NickName" HeaderResourceKey="General.Literal.CrmHistory_IdentityName">

<ItemTemplate>

<a href="/_SiteCommon/Handler/IdentityFinder.ashx?Id=<%# Eval("IdentityId") %>" target="_blank"><%# Eval("NickName") %></a>

</ItemTemplate>

</septa:LocalizedTemplateColumn>

<septa:LocalizedGridDataBoundColumn DataField="DRelatedToId" HeaderResourceKey="General.Literal.erja" />

<septa:LocalizedGridDataBoundColumn DataField="DRelatedToTypeIndex" HeaderResourceKey="General.Literal.ReferType" AllowSorting="false" />

<septa:LocalizedGridDataBoundColumn DataField="DCardtableStatusIndex" HeaderResourceKey="General.Literal.Status" AllowSorting="false" />

<septa:LocalizedGridDataBoundColumn DataField="DDoneCauseIndex" HeaderResourceKey="General.Literal.End" AllowSorting="false" />

<septa:LocalizedBoundColumn DataField="CreateDatePersian" HeaderResourceKey="General.Literal.CreateDate" />

<septa:LocalizedGridDataBoundColumn DataField="LifePathType" HeaderResourceKey="General.Literal.Type" AllowSorting="false" />

</Columns>

<NoRecordsTemplate>

<div class="clearfix text-center">

<septa:LocalizedLiteral runat="server" ResourceKey="Res.General.Literal.UcUserTasks_AnyCaseDefined"></septa:LocalizedLiteral>

</div>

</NoRecordsTemplate>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true" EnableAlternatingItems="false" AllowDragToGroup="True" AllowColumnsReorder="True">

<Selecting AllowRowSelect="true" EnableDragToSelectRows="true" />

<ClientEvents OnRowDblClick="RowDblClick" OnRowContextMenu="onRowContextMenu" />

<Resizing AllowColumnResize="true"></Resizing>

</ClientSettings>

</telerik:RadGrid>

And here is my columns:

public class LocalizedBoundColumn : GridBoundColumn

{

public LocalizedBoundColumn()

{

this.AutoPostBackOnFilter = true;

this.CurrentFilterFunction = GridKnownFunction.Contains;

this.AutoPostBackOnFilter = true;

this.ShowFilterIcon = false;

}

// ...

}
