DataGridviewComboBox列未正确显示该值 [英] DataGridviewComboBox column does not display the value properly

问题描述

大家好



我的网格中有DataGridviewComboBox列。

我可以保存该值。没有问题。

当我从数据库中恢复并将其分配给组合框时，分配给combox框的数据源无法正常显示。



例如



GroupId 1

团体名称亚洲



和它绑定到Combox.Datasource属性。

ValueMember是GroupId

显示会员是亚洲。



和我在数据库中保存1.

在编辑模式下，我检索1并分配给组合（如（DataGridViewComboboxcolumn）.datagrid.Rows [i] .cells [0] .value = 1;



组合必须在网格中的组合中显示亚洲。

而是在组合中显示1。



我也处理了Grid Event的DataError。



任何人都可以帮我解决问题。

解决方案

在RowDataBound事件中尝试这种方式它应该工作



protected void grdTourPricing_RowDataBound（o bject sender，GridViewRowEventArgs e）

{

if（e.Row.RowType == DataControlRowType.DataRow）

{

DropDownList ddlBranch = e.Row.FindControl（ddlBranch）作为DropDownList;



ddlBranch.DataSource = CacheMaster.getBranches（）;

ddlBranch.DataTextField =BranchName;



ddlBranch.DataValueField =BranchID;

ddlBranch.DataBind（）; < br $> b $ b

ddlBranch.SelectedValue =1;



}

}

Hi All

I have DataGridviewComboBox column in my Grid.
I am able to save the value. There is no issues.
When i rerieve from database and assign it to combobox, the datasource assigned to combox box does not display properly.

For Example

GroupId 1
Group Name Asia

And it is bound to Combox.Datasource Property.
ValueMember is GroupId
Display Member is Asia.

And i save 1 in database.
In edit mode i retrieve 1 and assign to combo like ((DataGridViewComboboxcolumn).datagrid.Rows[i].cells[0].value=1;

The combo has to display Asia in the combo in the grid.
Rather it displays 1 in the combo.

I have handled DataError of Grid Event too.

Can anyone help me to resolve the problem.

解决方案

Try this way in RowDataBound event it should work

protected void grdTourPricing_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlBranch = e.Row.FindControl("ddlBranch") as DropDownList;

ddlBranch.DataSource = CacheMaster.getBranches();
ddlBranch.DataTextField = "BranchName";

ddlBranch.DataValueField = "BranchID";
ddlBranch.DataBind();

ddlBranch.SelectedValue = "1";

}
}
