gridview

问题 I'm trying to bind a GridView HyperLinkField such that the bound column is used as a parameter value in the URL. Pretty standard stuff - nothing fancy, but the binding fails when the bound column contains a colon, i.e. : . I'm my particular case, this value is a string representing a duration of time, e.g. "14:35", or "1:07:19". Here's my GridView, with the time value bound to the HyperLinkField url. <asp:GridView ID="ResultsGridView" runat="server" AutoGenerateColumns="False" DataSourceID=

问题 I have an aspx.Page containing a gridview. The gridview is bound in code behind to a datasource only when no postback takes place and has enableviewstate = true (The page too). During a postback, the data bound to the gridview are lost. What could be the reason. Please ask if code is needed. 回答1: Solved it, problem was I made a Page.Databind() in the Page_Load event of the masterpage of the page with the gridview, so it bound the gridview during each postback without data.

问题 I load the gridview and the gridview has an edit and delete buttons. I click on Edit and I get, " ddlAssignedTo' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value I know that I am getting this error because the value fo ddlAssignedTo is null - nothing exists on the db for ddlAssignedTo. All I was trying to do is update the current value. So, my issue is this, if the current value is null, how do I assign a default value for

问题 I am binding a table to a gridview in asp.net as such grdIssues.DataSource = mdtIssues; grdIssues.DataBind(); The problem is I cannot then control the column width, asp.net seems to decided on it's own what width each column should be. Methods such as grdIssues.Columns[0].ItemStyle.Width = 100; grdIssues.Columns[1].ItemStyle.Width = 100; don't work because the columns are created dynamically. I cannot believe there isn't a way to do this short of manually creating each column and filling each

问题 In yii's CGridView I can get the current row number by using $row . But this returns the row index within the current page only. What I really need is to get the absolute row number among all pages. I am using yii, so my dreams should come true "easily", so I expect the answer should not guide me to add a special field to the data provider or access the pager and get the current page number and then multiply numbers bla bla bla. Thanks 回答1: Have you solved this? If not, I offer you the

问题 In ASP.NET Gridviews generate a table which generates a parent div container. This can break CSS layouts since there is no way to attach styles to the generated div. Is there a way to prevent the div from generating or a way to apply a style to it? This was asked and marked as resolved here but MS just said that the div is needed for the Paging and Sorting functionality. Am I to understand that if I want to use the paging and sorting functionality I can't wrap my own div around it and apply a

问题 I am creating a SharePoint web part in C# and part of it outputs a GridView control to the page. While I can get fairly extensive control over the way it is displayed by setting the CSS class of the GridView itself, what I would really like to do is be able to specify classes to certain specific td elements. I'm not sure how to go about doing this, or if it would be done at the time that the GridView is being populated with rows, or at the time the GridView is added to the page. In pseudocode
