InsertCommand, UpdateCommand, and Deletecommand not firing

Hello everyone,

I have a telerik Grid and when I try to use insert, update or delete the events on in the code behind never fire. The popup does go away though and it looks like the grid is being updated. This is what I have for the code:

<telerik:RadGrid

Does anyone have an Idea?

Controlling RadWindow Autosize Scroll Bars Better

Hi,

I've searched the threads on this issue, and I've found that there does not seem to be a good, consistent global solution for really benefitting from the Autosize property.

Overall, it appears to me that if you page grows just a tiny bit after the PageLoad event, you get unsightly scroll bars. The only way that I've been able to avoid that is to set the MinWidth/Height properties, which results in a somewhat time consuming "hit and miss" guessing game on the best sizes.

It seems to me, that there should be a way to add a "Autosize" buffer, or something like, maybe utilizing a CSS. Has anybody found a good way to tackle this globally, with CSS on the RadWindow, or the page itself, or by some other technique. Or, does anyone know how to run the Autosize() function at a time later than the PageLoad, to help deal with the issue of the page grows a little but with some client side rendering or something?

Check out the screen shot for some perspective on my problem.

Thanks a ton.

Selecting Image Properties, Selecting new Image Src - Src value not changed

Hello,

I've just started experiencing this. I have an Editor on a page. I go to HTML view, paste in some HTML, which includes an image, then switch to DESIGN view, right click on the image, select Properties, and then for the Image Src, I browse to select a replacement image. When I select it and click OK, it does NOT replace the value in the Image Src field. To get this to work, I have to clear the Image Src value, then browse and select the image.

Any ideas? Need more information?

Thank you.

Cannot get DataFormatString to show currency

Whatever I do (and I've tried many ideas already given in these forums) i cannot get my columns to show currencies, just plain numeric values.

I want my grid to show the "buyprice" and totalcost columns as "{0:C}" or "{0:$###.##}"

Here's my code:

.aspx

                    <telerik:RadGrid          
                    ID="RadGrid1" runat="server"         
                    Width="95%"         
                    OnNeedDataSource="RadGrid1_NeedDataSource"         
                    
                    
                    >         
                    <MasterTableView AutoGenerateColumns="false">         
                        <Columns>         
                            <telerik:GridBoundColumn DataField="id" Visible="false" ReadOnly="true"></telerik:GridBoundColumn>         
                            <telerik:GridBoundColumn DataField="symbol" HeaderText="Symbol"  ReadOnly="true" ></telerik:GridBoundColumn>         
                            <telerik:GridBoundColumn DataField="buyprice" HeaderText="Buy Price" DataType="System.Decimal" DataFormatString="{0:C}" ></telerik:GridBoundColumn>         
                            <telerik:GridBoundColumn DataField="totalcost" HeaderText="Total Cost" DataType="System.Decimal" DataFormatString="{0:C}" ></telerik:GridBoundColumn>         
                            <telerik:GridButtonColumn  ConfirmText="Are you sure?" ConfirmDialogType="Classic" ButtonType="ImageButton" ImageUrl="/images/delete.gif"CommandName="Delete">         
                            </telerik:GridButtonColumn>         
                        </Columns>         
                    </MasterTableView>         
                </telerik:RadGrid>         

.aspx.cs

                            protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)         
                    {         
                        string XMLFilePath = getXMLPath();         
                     
                        DataSet ds = new DataSet();         
                        ds.ReadXml(XMLFilePath);         
                     
                        DataView dv = new DataView(ds.Tables[0]);         
                        dv.Sort = "datecalculated DESC";         
                     
                        RadGrid1.DataSource = dv;         
                                 
                    }         

.xml

                    <?xml version="1.0" encoding="utf-8"?>         
            <calculations>         
              <calculation id="1" symbol="SYM1" buyprice="3.4" totalcost="831.483" datecalculated="06/30/2010" />         
              <calculation id="2" symbol="SYM2" buyprice="10.74" totalcost="1088" datecalculated="06/17/2010" />         
            </calculations>         

am I missing anything? Is my method of populating RadGrid1 causing this, can string formatting not be applied to boundcolumns? (I did try using GridNumericColumn, still without success).

check all checkboxes in radgrid on button click.

Hi,

check all checkboxes in radgrid on button click. button is placed outside radgrid. I tried thos method on button click.

                CheckBox chb;
                for (int i = 0; i < RadGrid1.Items.Count; i++)
                {
                    chb = (CheckBox)RadGrid1.Items[i].FindControl("chkSelectItem");
                    chb.Checked = true;
                }
This will fix the check boxes in the radgrid on that page. if I move to another page(pagination), it will be unchecked in there.
Thanks in advance.

Problem retrieving checked nodes on treeview

Hello,

I have a Treeview called RadTreeView1 which is already populated as follows, this is working perfect:

Do While RS.Read

If RS(0) = 1 Then

Dim Node As New RadTreeNode

Node.Text = (RS(2) & " " & RS(3) & " (" & RS(1) & ")")

Node.Value = RS(1)

Node.Checkable = True

RadTreeView1.Nodes.Add(Node)

Else

Dim foundNode As RadTreeNode = RadTreeView1.FindNodeByValue(RS(5))

If foundNode IsNot Nothing Then

Dim Node As New RadTreeNode

Node.Text = (RS(2) & " " & RS(3) & " (" & RS(1) & ")")

Node.Value = RS(1)

Node.Checkable = False

foundNode.Nodes.Add(Node)

End If

I've set the root values checkable=true and all the children as checkable=false (so the user can only check or uncheck the root values). Each node has a value which is an integer number.

What I need to do is to click on a button, and retrieve all those nodes that are checked. Im using the code below but its not working:

Imports Telerik.Web.UI

Partial Class Hierarchy_Compression

Inherits System.Web.UI.Page

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

Dim Compression As IList(Of RadTreeNode) = RadTreeView1.CheckedNodes

For Each node As RadTreeNode In Compression

If node.Checked = True Then

Response.Write(node.Value)

End If

Next

End Sub

End Class
