Forms Data Controls :: Programmatically Determine What Type Of Template Field To Put In Each Row In A Gridview?

Aug 11, 2010

I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.

Most characteristics require data to be entered in a text box but some a check box would be more appropriate.

My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?

Forms Data Controls :: Raise Click Event Of A Linkbutton Inside A Template Field That Was Created Programmatically

Jan 28, 2011

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

Forms Data Controls :: Template Field In Gridview Not Accessible?

Jan 10, 2011

I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:

[Code]....

Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:

Forms Data Controls :: GridView Template Field With Linkbutton Not Sorting?

Jun 22, 2010

I have a gridview control set up like so:

[Code]....

I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:

[Code]....

The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.

Forms Data Controls :: C# Dynamic Gridview Using Template Field As Control?

Mar 31, 2010

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.

After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

Forms Data Controls :: GridView RadioButtonList In Template Field (VS2005)?

Mar 6, 2011

I have a GridView that is bound to a DataTable containing questions. Each question has a possible score of 1 to 9 which is handled by a Template Field with a RadioButtonList databound to another DataTable (containing the values 1 to 9). This all works fine except as an added complication, some of the questions have an extra choice in another field. So the problem is how do I bind the second Template Field to a datasource that is dependent on the question. It's like passing a parameter to the datasource of the second Template Field, the value of the parameter being the Key Field of the particular row. Is this possible and if so, how do I do it

Forms Data Controls :: Error On Pressing Button In Gridview Template Field?

Feb 1, 2010

I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Below is my code

<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
<Columns>
<asp:BoundField DataField="Clientid" ItemStyle-Width="75px" />

Forms Data Controls :: Conditional GridView Mouseover - Mouseout Template Field?

Mar 9, 2011

This is what I have - it works:
<asp:GridView ID="GridView10" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource10"
<asp:TemplateField HeaderText="File Photo" SortExpression="Pic_Number">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Item_Count" HeaderText="Stock" SortExpression="Item_Count" InsertVisible="False" ReadOnly="True" >

Conceptually what I want: (item count is a BoundField called in the GridView )

<asp:GridView ID="GridView10" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource10"
<asp:TemplateField HeaderText="File Photo" SortExpression="Pic_Number">
<ItemTemplate>
( IF "Item_Count" > 50 )
<asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />
( IF "Item_Count" < 50 )
onmouseout : <asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/StockLow.jpg")) %>' />
onmouseover: <asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />

Forms Data Controls :: Formatting Datetime Returned By GridView Under The Template Field?

I need to format this date time into the format Day/Month/Year on the same template field.

I am avoiding doing this under SQL server because that will mean changing my data type in my dataset to string instead of data time which i do not want.

<asp:TemplateField HeaderText="Publish Date" SortExpression="PublishDate">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("PublishDate") %>'></asp:TextBox>

Forms Data Controls :: Getting Data Out Of GridView Where Checkbox Template Field Is Selected?

Jun 10, 2010

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

[Code]....

My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:

[Code]....

Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.
