Now my problem is at the time of binding the gridview i want to add a value to the specified column and the gridview has to be displayed by filtering based on the value given.

List<SpGetAllExamTypes_Result> lstExamTypes = objMdlClass.GetAllExamTypes(null).FindAll(F=>F.ExamName == ExamName);
foreach (SpGetAllExamTypes_Result objExam in lstExamTypes)
{
    ExamId = objExam.ExamTypeId;
}
List<SpGetConsolidatedExamReport_Result> lstexamMarks = objManage.GetExamAnalysisReport(
    Convert.ToInt32(CourseId), ExamId,
    ddlMasterAcademicYear.SelectedValue).FindAll(F=>F.SubjectId==Convert.ToInt32(SubjectId));

gvAnalysisView.DataSource = lstexamMarks;

推荐答案

查看演示网格 - 基本过滤 [ ^ ]。

Have a look at the demo Grid - Basic Filtering[^].

Quote：

该示例演示了Telerik RadGrid的过滤功能。可以使用 RadGrid.AllowFilteringByColumn 或 GridTableView.AllowFilteringByColumn 属性启用/禁用过滤。然后，每个支持过滤的列（GridBoundColumn，GridCheckBoxColumn等）在相应的标题下面显示一个过滤器框。

用户可以根据相应列属性中指定的规则设置过滤器表达式： FilterFormatString，CurrentFilterFunction，CurrentFilterValue 。按下过滤器按钮（过滤器框旁边）后，网格仅显示符合过滤条件的记录（关于所有过滤器框的设置）。

The example demonstrates the filtering capabilities of Telerik RadGrid. Filtering can be enabled/disabled using RadGrid.AllowFilteringByColumn or GridTableView.AllowFilteringByColumn properties. Then each column that supports filtering (GridBoundColumn, GridCheckBoxColumn, etc) shows a filter box beneath the corresponding header.
User can set a filter expression based on the rules specified in the corresponding column properties: FilterFormatString, CurrentFilterFunction, CurrentFilterValue . After pressing the filter button (next to the filter box) the grid displays only the records matching the filter criteria (regarding the settings of all filter boxes).
