I am trying to establish a master/detail relationship in my grid. For a reason I can not understand, the detail row appears in every master record. Can someone please point me to my mistake?

Here is my code:

<MasterTableView DataKeyNames="ID" DataSourceID="sqlBidDetail" EditMode="InPlace" CommandItemDisplay="Top" HierarchyLoadMode="ServerBind">

<DetailTables>

<telerik:GridTableView runat="server" AllowSorting="False" AutoGenerateColumns="True" DataKeyNames="DescriptionDetailID,BidDetailID" DataSourceID="sqlDescriptionDetail" EditMode="InPlace" CommandItemDisplay="Top" HierarchyLoadMode="ServerBind">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="tblDescriptionDetail.BidDetailID" MasterKeyField="ID" />

</ParentTableRelation>

</DetailTables

>

</MasterTableView>



and my 2 SQL data sources.




<asp:SqlDataSource ID="sqlBidDetail" runat="server" ConnectionString="<%$ ConnectionStrings:dbBidManager %>" 

SelectCommand="SELECT tblBidDetail.ID, tblBidDetail.BidID, tblBidDetail.ULAID, tblBidDetail.ProductID FROM tblBidDetail" />
 
<asp:SqlDataSource ID="sqlDescriptionDetail" runat="server" ConnectionString="<%$ ConnectionStrings:dbBidManager %>" 

SelectCommand="SELECT tblDescriptionDetail.DescriptionDetailID, tblDescriptionDetail.BidDetailID, tblDescriptionDetail.DescriptionTypeID FROM tblDescriptionDetail" />



There is a FK relationship between tblDescriptionDetail.BidDetailID and tblBidDetail.ID.  Note though that

tblDescriptionDetail.DescriptionDetailID is the primary key in that table.

Many things stopped functioning when moving from version 2011 to 2013

Hi,
unfortunately, some relevant functionality within RadGrid has been changed by you from version 2011 to 2013, that made the following things stop working:
1) paging in custom pager does not work anymore when other value has been set in the pagers' combo and then - navigating to different page: it resets to default value = 100 records per page
2) sorting does not work properly anymore, it's ignored when clicking the same column's header a second time sequentially
3) i have special custom buttons in template columns, they used to raise some popups and then, if confirmed, caused some postback action. Now it also does not work anymore.

And maybe other things I still have not noticed...

I cannot provide you with a sample for the moment, it's quite complicated to prepare it. I'd suggest you to tell what have you changed from the old verion to the new one, that could affect all this? What events I need to look at and maybe change something??

Grid Issue with Regular Expression and ExtractValuesFromItem Issue

I have a grid where on the ItemDataBound event, Im using some custom checking on the columns based on a list of objects from my database to see if the column can be edited or not. For the ones that can be edited, I then created a RegularExpressionValidator for the table cell along with setting the maxlength of the textbox when its in edit mode. This works perfectly until when I go to update the record. The way Im doing it is to grab the edited cell, build a gridRow and then remove that currently selected GridRow (the one being edited) and insert the new one using the new values from the edited row.

Here is my regular expression building

GridEditableItem item = e.Item as GridEditableItem;

//this is within a loop for the columns and another loop for my custom objects (metaData)

//set edit textbox max length

item[column.UniqueName].Enabled = true;

TextBox txtbx = (TextBox)item[column.UniqueName].Controls[0];

txtbx.MaxLength = metaData.MaxFieldLength;

//set regular expression for validation

RegularExpressionValidator regex = new RegularExpressionValidator();

GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor(column.UniqueName);

TableCell cell = (TableCell)editor.TextBoxControl.Parent;

editor.TextBoxControl.ID = "Validation" + column.UniqueName;

regex.Display = ValidatorDisplay.Dynamic;

regex.ControlToValidate = editor.TextBoxControl.ID;

regex.ForeColor = System.Drawing.Color.Red;

regex.ValidationExpression = @"^";

//custom regex expression building

regex.ValidationExpression = regex.ValidationExpression + @"$";

cell.Controls.Add(regex);

I get this values by during my grid_UpdateCommand event and call

//get selected row

GridEditableItem item = (GridEditableItem)e.Item;

//get values from the row

Hashtable newValues = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, item);

The row Im dealing with is working weird because during this call, the 2 columns textboxes that arent enabled (think like ReadOnly but the user can still see the values) are getting the new record values fine, but the 2 user editable textboxes are pulling back a null. When I turn the regular expression building off (comment it out), it pulls the records perfectly with all the column values. But when I have the regular expression building and checking on, it cant pull these values? Any reason why?
