[Solved] RadGrid - Accessing a cell on ItemDataBound

Hi

I have a RadGrid in which is some data. One of the columns of data is an nvarchar(MAX) filed in which there could be a little to a lot of text, at the prerogative of the user.

I'm trying find a way to read the text out of the grid, modify it to be truncated down to say the first 50 characters, and put it back in the cell.

I found this page on this site that talks about this exact issue. Alas the code here does work.

http://www.telerik.com/help/aspnet/grid/grdaccessingcellsandrows.html

The code on this page says I can read the cell value with this syntax

TableCell cell = dataItem["ColumnUniqueName"];

Alas this does not work as 'dataItem' does not exist.

I have tried this code in my grids ItemDataBound method,

protected void rgNotes_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem && e.Item.OwnerTableView.DataSourceID == "dsNotes")

{

TableCell cell = dataItem["NoteText"];

}

I even tried

TableCell cell = e.Item["NoteText"];

to no avail.

Anyone here have a solution to this, what should be a pretty obvious' issue?

I'm trying to change the minutesperrow property throught a combobox. Whenever i change the selected index of the combo it goes to server side code (vb.net) and do RadScheduler1.MinutesPerRow = RadComboBox2.SelectedValue but nothing happens. can anyone help me please?

radcombo code:

<telerik:RadComboBox ID="RadComboBox2" runat="server" AutoPostBack="True">

<Items>

<telerik:RadComboBoxItem Text="10min" Value="10" />

<telerik:RadComboBoxItem Text="20min" Value="20" />

<telerik:RadComboBoxItem Text="30min" Value="30" />

<telerik:RadComboBoxItem Text="40min" Value="40" />

How get the same expanded nodes after refresh the page

hi, is there any easy way to show the expanded nodes so that when you save the data, refresh the page and coming back, you still have the same nodes expanded as when you left?. In more details, I have a radtreeview and the user can add or edit nodes, expanding direferents branches. Then when the user clicks the Save button the data is saved on the database and the radtreeview is shown with all nodes collapsed.
In the code I must do some business cheks so when the user clicks the Save button I save the data, I deletes all nodes in the radtreeview, I create (populate) the radtreeview again bringing the data from the database; then I try to expand those nodes that were expanded but this last thing does not work.
The code I use is the next:

if (!DuplicateExists)

{

oBF.SaveManageLines(oAIlevel3List);

// Delete all nodes in the RadTreeView.

for (int a = 0; a < trTaxonomy.Nodes.Count; a++)

{

RadTreeNode oAICategory = trTaxonomy.Nodes[a];

for (int b = 0; b < oAICategory.Nodes.Count; b++)

{

RadTreeNode level1Node = oAICategory.Nodes[b];

if (level1Node.Nodes != null && level1Node.Nodes.Count > 0)

{

for (int c = 0; c < level1Node.Nodes.Count; c++)

{

RadTreeNode level2Node = level1Node.Nodes[c];

if (level2Node.Nodes != null && level2Node.Nodes.Count > 0)

{

for (int d = 0; d < level2Node.Nodes.Count; d++)

{

level2Node.Nodes.Clear();

}

level1Node.Nodes.Clear();

}

oAICategory.Nodes.Clear();

}

trTaxonomy.Nodes.Clear();

// Create the RadTreeeView again, bringing the values from the DB.

string[] ParamArray = new string[4];

int iLevelID = 1;

ParamArray[0] = iLevelID.ToString();

ParamArray[1] = "0";

ParamArray[2] = _PartnershipID.ToString();

ParamArray[3] = "1";

//BusinessFascade.Taxonomy oBF = new BusinessFascade.Taxonomy();

oBF = new BusinessFascade.Taxonomy();

dsAICategory = oBF.GetAllCategory(ParamArray);

foreach (AICategory ai in dsAICategory)

{

rootNode = new RadTreeNode(ai.Name);

rootNode.Value = ai.ID.ToString();

rootNode.Text = ai.Name + " (" + ai.TaxonomyCount + ")";

rootNode.Expanded = false;

rootNode.Checkable = false;

rootNode.AllowEdit = false;

rootNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

trTaxonomy.Nodes.Add(rootNode);

}

rootNode = new RadTreeNode("State");

rootNode.Value = "-999";

rootNode.Text = "State";

rootNode.Expanded = false;

rootNode.Checkable = false;

rootNode.AllowEdit = false;

rootNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

trTaxonomy.Nodes.Add(rootNode);

//Added node to show State Source Income Categories

rootNode = new RadTreeNode("State Source Schedule");

rootNode.Value = "-2";

rootNode.Text = "State Source Schedule";

rootNode.Expanded = false;

rootNode.Checkable = false;

rootNode.AllowEdit = false;

rootNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

trTaxonomy.Nodes.Add(rootNode);

// Expand the nodes. Review why is not working.

for (int w = 0; w < oAICategoryList.Count; w++)

{

ExpandNode(oAICategoryList[w]);

}

for (int z = 0; z < level1NodeList.Count; z++)

{

ExpandNode(level1NodeList[z]);

}

for (int y = 0; y < level2NodeList.Count; y++)

{

ExpandNode(level2NodeList[y]);

}

trTaxonomy.ExpandAllNodes();

}

Can't disable Telerik dropdown list with JQuery

I'm trying to use JQuery to enable a Telerik RadComboBox based on the selection of another Telerik RadComboBox.

Use case: User comes to page, ddlRequired is enabled, ddlListItems is disabled. If user selects "Required" then I want ddlListItems to then be enabled. Conversely, if "Optional" is selected, I want to disable ddlListItems.

<telerik:RadComboBox ID="ddlRequired" runat="server" Width="80px" ShowDropDownOnTextboxClick="true" EnableEmbeddedSkins="false" Skin="Classic"  OnClientSelectedIndexChanged="OnSelectedIndexChanged">
                    <Items>
                        <telerik:RadComboBoxItem Text="Required" Value="1" />
                        <telerik:RadComboBoxItem Text="Optional" Value="0" />
                    </Items>
                </telerik:RadComboBox>

                <telerik:RadComboBox ID="ddlListItems" runat="server" Width="200px" ShowDropDownOnTextboxClick="true" EnableEmbeddedSkins="false" Skin="Classic" Enabled="false">
                    <ItemTemplate>
                        <asp:TextBox ID="txtBoxQ1" runat="server" Width="160"/>
                    </ItemTemplate>
                    <Items>
                        <telerik:RadComboBoxItem />
                        <telerik:RadComboBoxItem />
                    </Items>
                </telerik:RadComboBox>

Here's where I've left off after trying several approaches. I realize it's not complete.

function OnSelectedIndexChanged()
{
    var ddl = $find("<%=ddlListItemsQ1.ClientID%>");
    ddl.set_enabled(false);
}

RadGrid with a Redirect

I'm trying to Display the selected record in a asp.formview on the same page as the RadGrid.
When I click the 'Select' (GridButtonColumn) Button no Redirect occurs.
If I type in the entire Page URL with a QueryString value (http://10.0.0.110/Listing1.aspx?id=781) the formview displays the record.

Here is the code:

<telerik:RadGrid ID="RadGrid1" runat="server"

AllowFilteringByColumn="True"

AllowPaging="True"

AllowSorting="True"

DataSourceID="SqlDataSource1"

GridLines="None"

Height="700px"

PageSize="20">

<ClientSettings AllowColumnsReorder="True">

<Selecting AllowRowSelect="True" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

</ClientSettings>

<MasterTableView datasourceid="SqlDataSource1" DataKeyNames="id">

<Columns>

<telerik:GridButtonColumn CommandName="Redirect" Text="Select" ButtonType="PushButton" UniqueName="ButtonColumn">

<HeaderStyle Width="70px" />

</telerik:GridButtonColumn>

</Columns>

<RowIndicatorColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<NoRecordsTemplate>

Sorry No Records Found, Modify your search and try again.

</NoRecordsTemplate>

</MasterTableView>

<PagerStyle Position="TopAndBottom" />

</telerik:RadGrid

CodeBehind:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "Redirect")

{

GridDataItem item = (GridDataItem)e.Item;

string value = item.GetDataKeyValue("id").ToString(); // Get the value in clicked row

// Save the required value in session

string url = "listing1.aspx?id=" + value;

Response.Redirect(url);

}

Thank you in advance!

Basic sort not working

Hi all,

This is the first time I have used Telerik RadGrid and I am having trouble getting the basic sort to work. I have a 5 column grid that is bound to an Entity Framework Entity. I will post all my code below. What is happening is, I click on the column header, I can see it go to the DelegateGrid_SortCommand code and the sortexpression and oldsortorder values look correct but after stepping out of the code the column is still not sorted. BTW. I got this code from the sample on the website.

I am not sure what I am missing. I have 3 different grids on this page that will all need to have sort working.

Thanks in advance you for your help.
