Restrict the Number of Columns in GridView

Restrict the Number of Columns in GridView

I am currently working with a gridview that displays product information. I'm trying to find a way to limit the description field so that only the first few lines are shown if it is too long, and also resize the image to fit into the image column while making the image and description columns slightly larger than the others.

Thank you!

<asp:GridView ID="gvProducts" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductId" OnRowDeleting="gvProducts_RowDeleting" OnSelectedIndexChanged="gvProducts_SelectedIndexChanged">
    <Columns>
        <asp:CommandField ShowSelectButton="True" />
        <asp:BoundField DataField="Productname" HeaderText="Name" />
        <asp:BoundField DataField="ProductDescription" HeaderText="Description"  />
        <asp:BoundField DataField="ProductSupplier" HeaderText="Supplier" />
        <asp:BoundField DataField="ProductCategory" HeaderText="Category" />
        <asp:BoundField DataField="ProductSubCategory" HeaderText="SubCategory" />
        <asp:BoundField DataField="ProductVAT" HeaderText="VAT" />
        <asp:BoundField DataField="ProductStock" HeaderText="Stock" />
        <asp:ImageField DataImageUrlField="ProductImage" HeaderText="Image"/>
        <asp:CheckBoxField DataField="ProductActive" HeaderText="Active" />
        <asp:CommandField ButtonType="Button" ShowDeleteButton="True" />
    </Columns>
    <SelectedRowStyle CssClass="selectedrow" />
</asp:GridView>

Answer №1

By employing CSS, we are able to restrict the display of description text, as demonstrated below:

<asp:GridView ID="gvProducts" runat="server" CssClass="GridCSS" AutoGenerateColumns="False" DataKeyNames="ProductId" OnRowDeleting="gvProducts_RowDeleting" OnSelectedIndexChanged="gvProducts_SelectedIndexChanged">
    <Columns>
-----------------------
-----------
---------
<asp:BoundField DataField="ProductDescription" HeaderText="Description" ItemStyle-CssClass="limittext" />
------------------
---------
-------------

</Columns>

</asp:GridView>

CSS styles used:

.GridCSS {
        table-layout:fixed; 
        width:100%; 
    }
    .GridCSS .limittext{
        overflow: hidden; 
        text-overflow: ellipsis; 
        white-space: nowrap;        
    }

One option is to utilize a mask for fw 4.5, or incorporate an external plugin such as Jquery Mask. Another approach could be to designate them as Template Item and insert code similar to <%# Eval("ProductDescription").SubString(0,50) %>

If you're utilizing the MVC framework, one way to modify the data in your GridView is by making changes in your controller before binding it to GW. However, if you're not using MVC, an alternative approach would be to set up a RowDataBound event where you can check if the description exceeds a specified character limit and then truncate it accordingly.

While this may not provide a complete solution, it could serve as inspiration for finding a workaround. Unfortunately, I am unable to provide code at the moment due to work commitments, but I can revisit later if no satisfactory answers are offered.

Here is a suggestion to handle long text:

<asp:TemplateField HeaderText="Description">
<ItemTemplate>

<%# Eval("ProductDescription").ToString().Length > 50 ? Eval("ProductDescription").ToString().Substring(0,50)+"..." : Eval("ProductDescription").ToString() %>

</ItemTemplate>
</asp:TemplateField>

If the text exceeds 50 characters, only display the first 50 characters and add ellipsis. Otherwise, show the entire text.

An alternative approach is to retrieve a short description from the database or Product object directly:

 public string ShortDescription
 {
    get 
    { 
        return ProductDescription.Length > 50 ? ProductDescription.Substring(0,50) : ProductDescription;
    }
 }
