}
}
private void BindMasterDataDropDown（）
{
//从valueTypeGroup表中读取ValueTypeGroupdata
List< valuetypegroup> valueTypeGroup = new List< valuetypegroup>（）;
valueTypeGroup = BLLMasterData.getAllValueTypeGroupData（）;
//将数据绑定到下拉列表
ddlMasterData.DataSource = valueTypeGroup;
ddlMasterData.DataTextField =ValueTypeGroupName;
ddlMasterData.DataValueField =ValueTypeGroupID;
ddlMasterData.DataBind（）;
ddlMasterData.Items.Insert（0，new ListItem（ - Please Select--，0））;
$
protected void ddlMasterData_SelectedIndexChanged（object sender，EventArgs e）
{
if（ddlMasterData。 SelectedValue ==0）
{
gvMasterData.Visible = false;
}
else
{
bindGridview（）;
}
}
私人voi d bindGridview（）
{
//从valueType表中读取ValueType
List< tendermanagement.model.valuetype> valueType = new List< tendermanagement.model.valuetype>（）;
valueType = BLLMasterData.getAllValueTypeData（）;
//绑定数据下拉
gvMasterData.DataSource = valueType;
gvMasterData.DataBind（）;
}
}

推荐答案
您必须对代码进行一些小的更改，例如
You have to do some minor changes in your code like
protected void ddlMasterData_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlMasterData.SelectedValue == "0")
{
gvMasterData.Visible = false;
}
else
{
bindGridview(Convert.ToInt32(ddlMasterData.SelectedValue));
}
}
private void bindGridview(int yourSelectedValue)
{
//select value from your database on the basis of the yourSelectedValue
List valueType = new List();
valueType = BLLMasterData.getAllValueTypeData();
//Bind the data to drop down
gvMasterData.DataSource = valueType;
gvMasterData.DataBind();
}
}
