Finding all selected RadGrid rows on all pages

I have a RadGrid with paging enabled. I select rows using a GridClientSelectColumn, When I click the save button, I want to do something with all the rows that are selected on all pages.

However, it was only looping through the rows on the current page. I tried to fix this by temporarily turning paging off, i.e.,

protected void btnSave_Click(object sender, EventArgs e)

{

RadGrid1.AllowPaging = false;

RadGrid1.Rebind();

foreach (GridDataItem item in RadGrid1.Items)

{

CheckBox chk = (CheckBox)item["Select"].Controls[0];

if (chk.Checked)

{

		...

}

RadGrid1.AllowPaging = true;

RadGrid1.Rebind();

}

This did indeed loop through every row on every page. However, every row is appearing as unchecked.

I then noticed that the selected rows are not persisted when I switch pages, so I used this method to persist them on the client side. So I have a Javascript array with the IDs of the selected rows. But is there a way to access that array in btnSave_Click?

It also looks like I can use this method to persist the selected rows on the server side. But then I'd have to select the rows with Command buttons, and I'd prefer not to do that if I don't have to.

RadPageLayout - Difference between Span and (SpanXs, SpanSm, SpanMd, SpanLg, SpanXl)

I have looked at the documentation for RadPageLayout to try to understand what is the difference between Span and (SpanXs, SpanSm, SpanMd, SpanLg, SpanXl) but the documentation only covers Span and does not explain what (SpanXs, SpanSm, SpanMd, SpanLg, SpanXl) is.

With Span for columns, it just says it is the size or width in grid units of the column. One grid equals 1/12 of the total width.

That is still not clear enough for me.

For example, what does it mean when a column has Span=4 and SpanMd=8?

Sincerely,

Keith Jackson

RadComboBox with FooterTemplate

I've a radcomboBox with footertemplate that allows me to add new items to the radcombobox. My RCB has onClientSelectedIndexChanged event that would fire when the selected index is changed. When I use footerTemplate to add new item - it does not fire this event. Can you please help.

<telerik:RadComboBox ID="rcbClass" runat="server" Width="400px" DropDownAutoWidth="Enabled" AllowCustomText="false" MarkFirstMatch="true" AutoPostBack="true" OnClientSelectedIndexChanged="ChangeEffortClassification">

<FooterTemplate>

<asp:TextBox ID="tbClassDetail" runat="server" ClientIDMode="Static"></asp:TextBox>

<asp:Button ID="btnAddClass" runat="server" Text="Add Classification" OnClick="btnClass_Click" ClientIDMode="Static" CausesValidation="false" OnClientClick="return validateGroupAndSetWaiting(this,'vgRCBFooter');" />

<asp:RequiredFieldValidator ID="rfvClassDetail" runat="server" ControlToValidate="tbClassDetail"

ErrorMessage="New Class cannot be blank" ValidationGroup="vgRCBFooter"></asp:RequiredFieldValidator>

</FooterTemplate>

</telerik:RadComboBox>

protected void btnClass_Click(object sender, EventArgs e)

{

Page.Validate("vgRCBFooter");

if (!Page.IsValid) return;

Button btnAddClass = sender as Button;

TextBox txtClassDetail = (TextBox)btnAddClass.NamingContainer.FindControl("tbClassDetail");

Telerik.Web.UI.RadComboBox rcbClassDetail = (Telerik.Web.UI.RadComboBox)btnAddClass.NamingContainer.Parent;

if (!String.IsNullOrEmpty(txtClassDetail.Text))

{

rcbClassDetail.Items.Insert(0, new Telerik.Web.UI.RadComboBoxItem(txtClassDetail.Text));

rcbClassDetail.SelectedIndex = 0;

txtClassDetail.Text = String.Empty;

}

Display metadata selected item.

Hi,

I am trying to use your file explorer and add some metadata to each file. Kind of simple archive.

I have attached a screenshot.

When the user select a file the meta data should be displayed on the right side.

I have problems with posting back and find the selected file to display the metadata for.

Autopostback not generating js in EditForm

I want the fields in a RadGrid EditForm to Autopostback. I am programmatically turning on Autopostback in Page_Load of the custom grid control. Here's the beginning of the grid ascx file:

<radG:RadGrid ID="G1" runat="server" EnableAJAX="True" EnableAJAXLoadingTemplate="True"
GridLines="None" OnDeleteCommand="RadGrid2_DeleteCommand" OnInsertCommand="RadGrid2_InsertCommand"
OnItemCommand="RadGrid2_ItemCommand" OnItemDataBound="RadGrid2_ItemDataBound"
OnNeedDataSource="RadGrid2_NeedDataSource" OnUpdateCommand="RadGrid2_UpdateCommand"
Skin="Web20" OnPreRender="G1_PreRender">
<AJAXLoadingTemplate>
 <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/loading7.gif" />
</AJAXLoadingTemplate>
<ClientSettings>
<Selecting AllowRowSelect="True" />
</ClientSettings>
<MasterTableView AllowSorting="True" AutoGenerateColumns="False" CommandItemDisplay="Top"
DataKeyNames="id" GridLines="Vertical">
<EditFormSettings EditFormType="Template">
<FormTemplate>

When the form is generated, the javascript for __doPostback is not added to the html. Is there some configuration thing that will cause Autopostback to fail to work? This is legacy code that I did not generate and I, frankly, don't understand it. But, on pages without a grid, I was able to add Autopostback in this way and it worked.

RadFilter - Filter function equivalent of "IN"

Hi,

I want to have a filter function in RadFilter equivalent to "IN" of SQL.
I should be able to select a field, select "IN" and provide the value as comma separated.
Is it available?
If not, is there a way to add it programmatically?
I am using RadFilterSqlQueryProvider to get the SQL query from the RadFilter. So please provide a solution with which the RadFilterSqlQueryProvider will be able to convert filter to SQL.

Awaiting Reply,
Thanks,
Sharon

Modify DrawRectangle Dialog

Hi,

I'm looking to make a few changes to the DrawRectangle tool dialog box, but am having difficulty.

Specifically, I would like to do the following.

* Change the title text (default is "Draw Rectangle")

* Remove the FillColor, DrawColor, and LineSize controls and set these values to Black, Black, and 1 respectively.

* When opening the dialog box, the user simply has to click the page to draw the rectangle and clicks apply when done.

Thanks!

How to get the preview string?

Hi,

Does the RadFilter control provide any function to return the filter string? for example:

(ShipCity = 'Irvine' AND OrderDate = '11/8/2010 12:00:00 AM')

I tried SaveSettings but it returns a unreadable string.

Additionally, if I have a string, how can I recreate the filter using my string? Is there any API I can use?

Thanks and have a great day.
Bruce
