In web application[asp.net], i am using telerik grid control, i am bind the data to grid when it is autocompletecolumns=true, now i want to bind the data autogeneratecolumns=false how can i place controls like in asp.net grid we use
<columns><asp:Templatefileds><ItemTemplate><asp:label id ="lblid" runat="Server"
Text='<%# Eval("Empid") #> /></ItemTemplage></asp:templae>
Radgrid also have template column like ASP gridview, you can use template columns as:
<MasterTableView ShowFooter="False">
<Columns>
<telerik:GridTemplateColumn UniqueName="TemplateColumn" SortExpression="CompanyName">
<ItemTemplate>
// Your Logic Here
</ItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
Hope this helps.
When the columns are not autocompleted, you must specify them as tags inside your Columns tag. You must specify the attributes for the tags which denote your columns and in the NeedDatasource event you fill your datasource.

I have a web page containing a grid view and need to display the data in the text box on page load instead of cell.
** Grid is read only
** There will not be edit/delete links.
is it possible ?
Thanks in advance.
You can use gridview templates fields, and you will find more about Using TemplateFields in the GridView Control
You can do something like this
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="txbType" Text='<%# Eval("fieldName") %>' Enabled="false" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
In here <%# Eval("fieldName") %> -- fieldName should be the value need to be display from your DB
You have to add TemplateFields to the GridView and bind the TextBoxe(s) into ItemTemplate of each TemplateField column.
I am trying to show a large amount of data in gridview but the problem is that everytime data increase the gridview row size increase automatically.
is there any possible way that the data which is stored in my MS access Database display in multi line instead of one single long line.
If you are populating the GridView using AutoGenerate="true" make if AutoGenerate="false"
Then use asp:TemplateField to populate the GridView.
Now give an ItemStyle-Width and ItemStyle-Wrap.
<asp:TemplateField ItemStyle-Width="50px" ItemStyle-Wrap="true">
<ItemTemplate>
<asp:Label ID="ShipNameLabel" runat="server" Text='<%# Eval("ShipName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The telerik gridview control supports multi line rows http://www.telerik.com/products/aspnet-ajax/grid.aspx.
However, this does cost. You may try displaying only a few columns, then the user has to click on the row to see the other information in a form view.
Don't understand your question fully but it sounds as a Repeater might work better for you where you have more control of the layout of the rendering.
If it is the amount of rows that are the problem I do recommend to introduce paging to limit amount of row displayed at once.
Update:
1) Set up a CssClass for the GridView itself and include the table-layout:fixed style. This tells the browser that you're going to specify the width of each cell. You may also want to include the overall width of the grid here as I mention in (3).
2) The first row of the table sets the width for each cell, and that's usually the HEADER row, not the item row, so use either HeaderStyle-CssClass or HeaderStyle-Width to set the width of the cell.
3) Make certain the table itself is wide enough to hold all of the cells. I added up all of my cell widths and used that to set the width via the CssClass attribute on the GridView.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns='false'>
<Columns>
<asp:BoundField DataField='Name' />
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat='server' ReadOnly="true" BorderStyle="None"
TextMode="MultiLine" Text='<%# Bind("Description") %>'
>
</asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
You may have to add some styling to gridview via .skin or css
I have one GridView in a .aspx page, and am showing dynamic data in this grid, setting AutoGenerateColumns="True".
Depending upon which of the options the user selects in a combo box, I am binding different DataTables to the GridView. For example, if the user selects Persons then I am fetching the Persons DataTable, and if the user selects Products then I am fetching Products DataTable.
How can I show a float or double number in 2 decimal places in GridView?
The bound column should have a DataFormatString column. You could do something like:
DataFormatString="{0:0.00}"
Numeric Custom Format Strings
UPDATE
In the case of AutoGenerateColumns="true"... I'd have to know more specifics about what you're binding, but here are some avenues to explore:
I'm not sure if GridView will
respect the DataFormatAttribute in
Data Annotations. If you are binding
an object, and GridView respects
that attribute, that might be one
route to go.
Wire the RowDataBound event and
inspect each column for potential
decimal values, and format that way.
you can write BoundField in GridView:
<asp:BoundField DataField="amount" DataFormatString="{0:n}" />
you can also write TemplateField in GridView
<asp:TemplateField>
<ItemTemplate>
<%#Eval("amount","{0:n}")%>
</ItemTemplate>
</asp:TemplateField>
You can do DataFormatString="{0:n2}"in your boundfield
This works on a template column, say if you want a decimal out to two places for a ratio (like 1:3)
<%# Eval("somedatacolumn", "1:{0:.##}").ToString() %>
If you use DataFormatString and it does not seem to be doing the trick, add HtmlEncode = "false", for example:
<asp:BoundField DataField="DateScheduled" HeaderText="Date Created" DataFormatString="{0:D}" HtmlEncode="false"/> // date format
<asp:BoundField DataField="Amount" HeaderText="Pay This Amount" DataFormatString="{0:F}" HtmlEncode="false"/> // number format
There are two easy ways to format things in a GridView. The first is given in a previous answer - use the DataFormatString. The second, which sounds like it applies to your situation, where you are dynamically loading the grid, is to change the data going into the grid.
So, rather than returning a number and trying to format it, return a formatted number and let the GridView display it.
<asp:TemplateField HeaderText="Prev Salary" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblGrdSalary" runat="server" Text='<%#Bind("Salary", "{0:n}") %>'></asp:Label>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center"></HeaderStyle>
<ItemStyle HorizontalAlign="Center" Width="70px" />
</asp:TemplateField>
I am filling a GridView with the data table but on each row I want a check box how can I achieve this?
<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="Left">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked="false" />
</ItemTemplate>
</asp:TemplateField>
Use this, you will find what you want!
You could use a < asp:TemplateColumn > or, depending on your desired functionality, opt for a repeater control instead.
Right click the grid view and add a template column. Inside that column, you are able to put whatever you want - including a checkbox.
I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time.
I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do?
Thank you in advance.
If you are using a bound textbox in a template field in your detailsview you can then select it by:
$("[id$='MyTextBox']");
Which will find the textbox bound to MyFieldName as below.
<asp:DetailsView ID="DetailsView1" runat="server">
<Fields>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="MyTextBox" Text='<%# Bind("MyFieldName")%>' runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Fields>
</asp:DetailsView>
Whatever guff asp.net adds onto the begining of the id won't matter because jQuery $= mean "ends with".
there may be a better way, but when I've needed an id available for js work, I just convert the bound field to a templated field. you can then give the textbox the id of your choice. keep in mind when rendered the id will be expanded with the id of the parent control.
